  - All versions of package trim are vulnerable to Regular Expression Denial of Service (ReDoS) via trim().
    (CVE-2020-7753)

  - ansi-regex is vulnerable to Inefficient Regular Expression Complexity (CVE-2021-3807)

  - json-schema is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype     Pollution') (CVE-2021-3918)

  - In Async before 2.6.4 and 3.x before 3.2.2, a malicious user can obtain privileges via the mapValues()     method, aka lib/internal/iterator.js createObjectIterator prototype pollution. (CVE-2021-43138)

  - follow-redirects is vulnerable to Exposure of Private Personal Information to an Unauthorized Actor     (CVE-2022-0155)

  - In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because     an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)

  - Grafana is an open-source platform for monitoring and observability. Versions on the 8.x and 9.x branch     prior to 9.0.3, 8.5.9, 8.4.10, and 8.3.10 are vulnerable to stored cross-site scripting via the Unified     Alerting feature of Grafana. An attacker can exploit this vulnerability to escalate privilege from editor     to admin by tricking an authenticated admin to click on a link. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10     contain a patch. As a workaround, it is possible to disable alerting or use legacy alerting.
    (CVE-2022-31097)

  - Grafana is an open-source platform for monitoring and observability. In versions 5.3 until 9.0.3, 8.5.9,     8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana     instance via a configured OAuth IdP which provides a login name to take over the account of another user     in that Grafana instance. This can occur when the malicious user is authorized to log in to Grafana via     OAuth, the malicious user's external user id is not already associated with an account in Grafana, the     malicious user's email address is not already associated with an account in Grafana, and the malicious     user knows the Grafana username of the target user. If these conditions are met, the malicious user can     set their username in the OAuth provider to that of the target user, then go through the OAuth flow to log     in to Grafana. Due to the way that external and internal user accounts are linked together during login,     if the conditions above are all met then the malicious user will be able to log in to the target user's     Grafana account. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a     workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users     authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.
    (CVE-2022-31107)

  - An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage     will take significant time to parse. (CVE-2022-32149)

  - Grafana is an open-source platform for monitoring and observability. Versions prior to 9.1.6 and 8.5.13     are vulnerable to an escalation from admin to server admin when auth proxy is used, allowing an admin to     take over the server admin account and gain full control of the grafana instance. All installations should     be upgraded as soon as possible. As a workaround deactivate auth proxy following the instructions at:
    https://grafana.com/docs/grafana/latest/setup-grafana/configure-security/configure-authentication/auth-     proxy/ (CVE-2022-35957)

  - Grafana is an open-source platform for monitoring and observability. In versions prior to 8.5.13, 9.0.9,     and 9.1.6, Grafana is subject to Improper Preservation of Permissions resulting in privilege escalation on     some folders where Admin is the only used permission. The vulnerability impacts Grafana instances where     RBAC was disabled and enabled afterwards, as the migrations which are translating legacy folder     permissions to RBAC permissions do not account for the scenario where the only user permission in the     folder is Admin, as a result RBAC adds permissions for Editors and Viewers which allow them to edit and     view folders accordingly. This issue has been patched in versions 8.5.13, 9.0.9, and 9.1.6. A workaround     when the impacted folder/dashboard is known is to remove the additional permissions manually.
    (CVE-2022-36062)

  - Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion     or denial of service. The parsed regexp representation is linear in the size of the input, but in some     cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger     amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular     expressions whose representation would use more space than that are rejected. Normal use of regular     expressions is unaffected. (CVE-2022-41715)

  - Prometheus Exporter Toolkit is a utility package to build exporters. Prior to versions 0.7.2 and 0.8.2, if     someone has access to a Prometheus web.yml file and users' bcrypted passwords, they can bypass security by     poisoning the built-in authentication cache. Versions 0.7.2 and 0.8.2 contain a fix for the issue. There     is no workaround, but attacker must have access to the hashed password to use this functionality.
    (CVE-2022-46146)

  - Grafana is an open-source platform for monitoring and observability. Starting with the 9.1 branch, Grafana     introduced the ability to search for a JWT in the URL query parameter auth_token and use it as the     authentication token. By enabling the url_login configuration option (disabled by default), a JWT might     be sent to data sources. If an attacker has access to the data source, the leaked token could be used to     authenticate to Grafana. (CVE-2023-1387)

  - Grafana is an open-source platform for monitoring and observability. Grafana had a stored XSS     vulnerability in the Graphite FunctionDescription tooltip. The stored XSS vulnerability was possible due     the value of the Function Description was not properly sanitized. An attacker needs to have control over     the Graphite data source in order to manipulate a function description and a Grafana admin needs to     configure the data source, later a Grafana user needs to select a tampered function and hover over the     description. Users may upgrade to version 8.5.22, 9.2.15 and 9.3.11 to receive a fix. (CVE-2023-1410)

The remote AlmaLinux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALSA-2023:2167 advisory.

  - In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because     an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)

  - Requests forwarded by ReverseProxy include the raw query parameters from the inbound request, including     unparseable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy     forwards a parameter with an unparseable value. After fix, ReverseProxy sanitizes the query parameters in     the forwarded query when the outbound request's Form field is set after the ReverseProxy. Director     function returns, indicating that the proxy has parsed the query parameters. Proxies which do not parse     query parameters continue to forward the original query parameters unchanged. (CVE-2022-2880)

  - Grafana is an open-source platform for monitoring and observability. Versions prior to 9.1.6 and 8.5.13     are vulnerable to an escalation from admin to server admin when auth proxy is used, allowing an admin to     take over the server admin account and gain full control of the grafana instance. All installations should     be upgraded as soon as possible. As a workaround deactivate auth proxy following the instructions at:
    https://grafana.com/docs/grafana/latest/setup-grafana/configure-security/configure-authentication/auth-     proxy/ (CVE-2022-35957)

  - Grafana is an open source data visualization platform for metrics, logs, and traces. Versions prior to     9.1.8 and 8.5.14 allow one user to block another user's login attempt by registering someone else'e email     address as a username. A Grafana user's username and email address are unique fields, that means no other     user can have the same username or email address as another user. A user can have an email address as a     username. However, the login system allows users to log in with either username or email address. Since     Grafana allows a user to log in with either their username or email address, this creates an usual     behavior where `user_1` can register with one email address and `user_2` can register their username as     `user_1`'s email address. This prevents `user_1` logging into the application since `user_1`'s password     won't match with `user_2`'s email address. Versions 9.1.8 and 8.5.14 contain a patch. There are no     workarounds for this issue. (CVE-2022-39229)

  - Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion     or denial of service. The parsed regexp representation is linear in the size of the input, but in some     cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger     amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular     expressions whose representation would use more space than that are rejected. Normal use of regular     expressions is unaffected. (CVE-2022-41715)

  - Grafana is an open-source platform for monitoring and observability. In versions 5.3 until 9.0.3, 8.5.9,     8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana     instance via a configured OAuth IdP which provides a login name to take over the account of another user     in that Grafana instance.

Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a     workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users     authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4428-1 advisory.

  - ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before     1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon     crash. This occurs because a return value is not properly managed in a certain situation. (CVE-2021-36222)

  - In order to decrypt SM2 encrypted data an application is expected to call the API function     EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the     out parameter can be NULL and, on exit, the outlen parameter is populated with the buffer size     required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer     and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the out parameter. A bug     in the implementation of the SM2 decryption code means that the calculation of the buffer size required to     hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size     required by the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the     application a second time with a buffer that is too small. A malicious attacker who is able present SM2     content for decryption to an application could cause attacker chosen data to overflow the buffer by up to     a maximum of 62 bytes altering the contents of other data held after the buffer, possibly changing     application behaviour or causing the application to crash. The location of the buffer is application     dependent but is typically heap allocated. Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k).
    (CVE-2021-3711)

  - Grafana is an open-source platform for monitoring and observability. In affected versions if an attacker     is able to convince a victim to visit a URL referencing a vulnerable page, arbitrary JavaScript content     may be executed within the context of the victim's browser. The user visiting the malicious link must be     unauthenticated and the link must be for a page that contains the login button in the menu bar. The url     has to be crafted to exploit AngularJS rendering and contain the interpolation binding for AngularJS     expressions. AngularJS uses double curly braces for interpolation binding: {{ }} ex:
    {{constructor.constructor(alert(1)')()}}. When the user follows the link and the page renders, the login     button will contain the original link with a query parameter to force a redirect to the login page. The     URL is not validated and the AngularJS rendering engine will execute the JavaScript expression contained     in the URL. Users are advised to upgrade as soon as possible. If for some reason you cannot upgrade, you     can use a reverse proxy or similar to block access to block the literal string {{ in the path.
    (CVE-2021-41174)

  - Grafana is an open-source platform for monitoring and observability. In affected versions when the fine-     grained access control beta feature is enabled and there is more than one organization in the Grafana     instance admins are able to access users from other organizations. Grafana 8.0 introduced a mechanism     which allowed users with the Organization Admin role to list, add, remove, and update users' roles in     other organizations in which they are not an admin. With fine-grained access control enabled, organization     admins can list, add, remove and update users' roles in another organization, where they do not have     organization admin role. All installations between v8.0 and v8.2.3 that have fine-grained access control     beta enabled and more than one organization should be upgraded as soon as possible. If you cannot upgrade,     you should turn off the fine-grained access control using a feature flag. (CVE-2021-41244)

  - Grafana is an open-source platform for monitoring and observability. Grafana versions 8.0.0-beta1 through     8.3.0 (except for patched versions) iss vulnerable to directory traversal, allowing access to local files.
    The vulnerable URL path is: `<grafana_host_url>/public/plugins//`, where is the plugin ID for any     installed plugin. At no time has Grafana Cloud been vulnerable. Users are advised to upgrade to patched     versions 8.0.7, 8.1.8, 8.2.7, or 8.3.1. The GitHub Security Advisory contains more information about     vulnerable URL paths, mitigation, and the disclosure timeline. (CVE-2021-43798)

  - Grafana is an open-source platform for monitoring and observability. Grafana prior to versions 8.3.2 and     7.5.12 contains a directory traversal vulnerability for fully lowercase or fully uppercase .md files. The     vulnerability is limited in scope, and only allows access to files with the extension .md to authenticated     users only. Grafana Cloud instances have not been affected by the vulnerability. Users should upgrade to     patched versions 8.3.2 or 7.5.12. For users who cannot upgrade, running a reverse proxy in front of     Grafana that normalizes the PATH of the request will mitigate the vulnerability. The proxy will have to     also be able to handle url encoded paths. Alternatively, for fully lowercase or fully uppercase .md files,     users can block /api/plugins/.*/markdown/.* without losing any functionality beyond inlined plugin help     text. (CVE-2021-43813)

  - Grafana is an open-source platform for monitoring and observability. Grafana prior to versions 8.3.2 and     7.5.12 has a directory traversal for arbitrary .csv files. It only affects instances that have the     developer testing tool called TestData DB data source enabled and configured. The vulnerability is limited     in scope, and only allows access to files with the extension .csv to authenticated users only. Grafana     Cloud instances have not been affected by the vulnerability. Versions 8.3.2 and 7.5.12 contain a patch for     this issue. There is a workaround available for users who cannot upgrade. Running a reverse proxy in front     of Grafana that normalizes the PATH of the request will mitigate the vulnerability. The proxy will have to     also be able to handle url encoded paths. (CVE-2021-43815)

  - Grafana is an open-source platform for monitoring and observability. In Grafana Enterprise, the Request     security feature allows list allows to configure Grafana in a way so that the instance doesn't call or     only calls specific hosts. The vulnerability present starting with version 7.4.0-beta1 and prior to     versions 7.5.16 and 8.5.3 allows someone to bypass these security configurations if a malicious datasource     (running on an allowed host) returns an HTTP redirect to a forbidden host. The vulnerability only impacts     Grafana Enterprise when the Request security allow list is used and there is a possibility to add a custom     datasource to Grafana which returns HTTP redirects. In this scenario, Grafana would blindly follow the     redirects and potentially give secure information to the clients. Grafana Cloud is not impacted by this     vulnerability. Versions 7.5.16 and 8.5.3 contain a patch for this issue. There are currently no known     workarounds. (CVE-2022-29170)

  - Grafana is an open-source platform for monitoring and observability. Versions on the 8.x and 9.x branch     prior to 9.0.3, 8.5.9, 8.4.10, and 8.3.10 are vulnerable to stored cross-site scripting via the Unified     Alerting feature of Grafana. An attacker can exploit this vulnerability to escalate privilege from editor     to admin by tricking an authenticated admin to click on a link. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10     contain a patch. As a workaround, it is possible to disable alerting or use legacy alerting.
    (CVE-2022-31097)

  - Grafana is an open-source platform for monitoring and observability. In versions 5.3 until 9.0.3, 8.5.9,     8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana     instance via a configured OAuth IdP which provides a login name to take over the account of another user     in that Grafana instance. This can occur when the malicious user is authorized to log in to Grafana via     OAuth, the malicious user's external user id is not already associated with an account in Grafana, the     malicious user's email address is not already associated with an account in Grafana, and the malicious     user knows the Grafana username of the target user. If these conditions are met, the malicious user can     set their username in the OAuth provider to that of the target user, then go through the OAuth flow to log     in to Grafana. Due to the way that external and internal user accounts are linked together during login,     if the conditions above are all met then the malicious user will be able to log in to the target user's     Grafana account. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a     workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users     authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.
    (CVE-2022-31107)

  - Grafana is an open-source platform for monitoring and observability. Versions prior to 9.1.6 and 8.5.13     are vulnerable to an escalation from admin to server admin when auth proxy is used, allowing an admin to     take over the server admin account and gain full control of the grafana instance. All installations should     be upgraded as soon as possible. As a workaround deactivate auth proxy following the instructions at:
    https://grafana.com/docs/grafana/latest/setup-grafana/configure-security/configure-authentication/auth-     proxy/ (CVE-2022-35957)

  - Grafana is an open-source platform for monitoring and observability. In versions prior to 8.5.13, 9.0.9,     and 9.1.6, Grafana is subject to Improper Preservation of Permissions resulting in privilege escalation on     some folders where Admin is the only used permission. The vulnerability impacts Grafana instances where     RBAC was disabled and enabled afterwards, as the migrations which are translating legacy folder     permissions to RBAC permissions do not account for the scenario where the only user permission in the     folder is Admin, as a result RBAC adds permissions for Editors and Viewers which allow them to edit and     view folders accordingly. This issue has been patched in versions 8.5.13, 9.0.9, and 9.1.6. A workaround     when the impacted folder/dashboard is known is to remove the additional permissions manually.
    (CVE-2022-36062)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4437-1 advisory.

  - ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before     1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon     crash. This occurs because a return value is not properly managed in a certain situation. (CVE-2021-36222)

  - In order to decrypt SM2 encrypted data an application is expected to call the API function     EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the     out parameter can be NULL and, on exit, the outlen parameter is populated with the buffer size     required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer     and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the out parameter. A bug     in the implementation of the SM2 decryption code means that the calculation of the buffer size required to     hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size     required by the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the     application a second time with a buffer that is too small. A malicious attacker who is able present SM2     content for decryption to an application could cause attacker chosen data to overflow the buffer by up to     a maximum of 62 bytes altering the contents of other data held after the buffer, possibly changing     application behaviour or causing the application to crash. The location of the buffer is application     dependent but is typically heap allocated. Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k).
    (CVE-2021-3711)

  - Grafana is an open-source platform for monitoring and observability. In affected versions if an attacker     is able to convince a victim to visit a URL referencing a vulnerable page, arbitrary JavaScript content     may be executed within the context of the victim's browser. The user visiting the malicious link must be     unauthenticated and the link must be for a page that contains the login button in the menu bar. The url     has to be crafted to exploit AngularJS rendering and contain the interpolation binding for AngularJS     expressions. AngularJS uses double curly braces for interpolation binding: {{ }} ex:
    {{constructor.constructor(alert(1)')()}}. When the user follows the link and the page renders, the login     button will contain the original link with a query parameter to force a redirect to the login page. The     URL is not validated and the AngularJS rendering engine will execute the JavaScript expression contained     in the URL. Users are advised to upgrade as soon as possible. If for some reason you cannot upgrade, you     can use a reverse proxy or similar to block access to block the literal string {{ in the path.
    (CVE-2021-41174)

  - Grafana is an open-source platform for monitoring and observability. In affected versions when the fine-     grained access control beta feature is enabled and there is more than one organization in the Grafana     instance admins are able to access users from other organizations. Grafana 8.0 introduced a mechanism     which allowed users with the Organization Admin role to list, add, remove, and update users' roles in     other organizations in which they are not an admin. With fine-grained access control enabled, organization     admins can list, add, remove and update users' roles in another organization, where they do not have     organization admin role. All installations between v8.0 and v8.2.3 that have fine-grained access control     beta enabled and more than one organization should be upgraded as soon as possible. If you cannot upgrade,     you should turn off the fine-grained access control using a feature flag. (CVE-2021-41244)

  - Grafana is an open-source platform for monitoring and observability. Grafana versions 8.0.0-beta1 through     8.3.0 (except for patched versions) iss vulnerable to directory traversal, allowing access to local files.
    The vulnerable URL path is: `<grafana_host_url>/public/plugins//`, where is the plugin ID for any     installed plugin. At no time has Grafana Cloud been vulnerable. Users are advised to upgrade to patched     versions 8.0.7, 8.1.8, 8.2.7, or 8.3.1. The GitHub Security Advisory contains more information about     vulnerable URL paths, mitigation, and the disclosure timeline. (CVE-2021-43798)

  - Grafana is an open-source platform for monitoring and observability. Grafana prior to versions 8.3.2 and     7.5.12 contains a directory traversal vulnerability for fully lowercase or fully uppercase .md files. The     vulnerability is limited in scope, and only allows access to files with the extension .md to authenticated     users only. Grafana Cloud instances have not been affected by the vulnerability. Users should upgrade to     patched versions 8.3.2 or 7.5.12. For users who cannot upgrade, running a reverse proxy in front of     Grafana that normalizes the PATH of the request will mitigate the vulnerability. The proxy will have to     also be able to handle url encoded paths. Alternatively, for fully lowercase or fully uppercase .md files,     users can block /api/plugins/.*/markdown/.* without losing any functionality beyond inlined plugin help     text. (CVE-2021-43813)

  - Grafana is an open-source platform for monitoring and observability. Grafana prior to versions 8.3.2 and     7.5.12 has a directory traversal for arbitrary .csv files. It only affects instances that have the     developer testing tool called TestData DB data source enabled and configured. The vulnerability is limited     in scope, and only allows access to files with the extension .csv to authenticated users only. Grafana     Cloud instances have not been affected by the vulnerability. Versions 8.3.2 and 7.5.12 contain a patch for     this issue. There is a workaround available for users who cannot upgrade. Running a reverse proxy in front     of Grafana that normalizes the PATH of the request will mitigate the vulnerability. The proxy will have to     also be able to handle url encoded paths. (CVE-2021-43815)

  - Grafana is an open-source platform for monitoring and observability. In Grafana Enterprise, the Request     security feature allows list allows to configure Grafana in a way so that the instance doesn't call or     only calls specific hosts. The vulnerability present starting with version 7.4.0-beta1 and prior to     versions 7.5.16 and 8.5.3 allows someone to bypass these security configurations if a malicious datasource     (running on an allowed host) returns an HTTP redirect to a forbidden host. The vulnerability only impacts     Grafana Enterprise when the Request security allow list is used and there is a possibility to add a custom     datasource to Grafana which returns HTTP redirects. In this scenario, Grafana would blindly follow the     redirects and potentially give secure information to the clients. Grafana Cloud is not impacted by this     vulnerability. Versions 7.5.16 and 8.5.3 contain a patch for this issue. There are currently no known     workarounds. (CVE-2022-29170)

  - Grafana is an open-source platform for monitoring and observability. Versions on the 8.x and 9.x branch     prior to 9.0.3, 8.5.9, 8.4.10, and 8.3.10 are vulnerable to stored cross-site scripting via the Unified     Alerting feature of Grafana. An attacker can exploit this vulnerability to escalate privilege from editor     to admin by tricking an authenticated admin to click on a link. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10     contain a patch. As a workaround, it is possible to disable alerting or use legacy alerting.
    (CVE-2022-31097)

The remote CentOS Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the grafana-9.0.9-1.el9 build changelog.

  - XSS (CVE-2021-23648)

  - Grafana is an open source data visualization platform. In affected versions unauthenticated and     authenticated users are able to view the snapshot with the lowest database key by accessing the literal     paths: /dashboard/snapshot/:key, or /api/snapshots/:key. If the snapshot public_mode configuration     setting is set to true (vs default of false), unauthenticated users are able to delete the snapshot with     the lowest database key by accessing the literal path: /api/snapshots-delete/:deleteKey. Regardless of the     snapshot public_mode setting, authenticated users are able to delete the snapshot with the lowest     database key by accessing the literal paths: /api/snapshots/:key, or /api/snapshots-delete/:deleteKey. The     combination of deletion and viewing enables a complete walk through all snapshot data while resulting in     complete snapshot data loss. This issue has been resolved in versions 8.1.6 and 7.5.11. If for some reason     you cannot upgrade you can use a reverse proxy or similar to block access to the literal paths:
    /api/snapshots/:key, /api/snapshots-delete/:deleteKey, /dashboard/snapshot/:key, and /api/snapshots/:key.
    They have no normal function and can be disabled without side effects. (CVE-2021-39226)

  - directory traversal vulnerability for *.md files (CVE-2021-43813)

  - net/http: limit growth of header canonicalization cache (CVE-2021-44716)

  - net/http: improper sanitization of Transfer-Encoding header (CVE-2022-1705)

  - go/parser: stack exhaustion in all Parse* functions (CVE-2022-1962)

  - Forward OAuth Identity Token can allow users to access some data sources (CVE-2022-21673)

  - client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package     in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version     1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential     memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an     instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`;
    not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our     middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`.
    client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including     removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected     promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method     given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow     a limited set of methods. (CVE-2022-21698)

  - XSS vulnerability in data source handling (CVE-2022-21702)

  - CSRF vulnerability can lead to privilege escalation (CVE-2022-21703)

  - IDOR vulnerability can lead to information disclosure (CVE-2022-21713)

  - encoding/xml: stack exhaustion in Decoder.Skip (CVE-2022-28131)
