| CVE-2023-23596 | jc21 NGINX Proxy Manager through 2.9.19 allows OS command injection. When creating an access list, the backend builds an htpasswd file with crafted username and/or password input that is concatenated without any validation, and is directly passed to the exec command, potentially allowing an authenticated attacker to execute arbitrary commands on the system. NOTE: this is not part of any NGINX software shipped by F5. | high |
| CVE-2026-1642 | A vulnerability exists in NGINX OSS and NGINX Plus when configured to proxy to upstream Transport Layer Security (TLS) servers. An attacker with a man-in-the-middle (MITM) position on the upstream server side—along with conditions beyond the attacker's control—may be able to inject plain text data into the response from an upstream proxied server.

| CVE-2020-12443 | BigBlueButton before 2.2.6 allows remote attackers to read arbitrary files because the presfilename (lowercase) value can be a .pdf filename while the presFilename (mixed case) value has a ../ sequence. This can be leveraged for privilege escalation via a directory traversal to bigbluebutton.properties. NOTE: this issue exists because of an ineffective mitigation to CVE-2020-12112 in which there was an attempted fix within an NGINX configuration file, without considering that the relevant part of NGINX is case-insensitive. | critical |
| CVE-2020-29238 | An integer buffer overflow in the Nginx webserver of ExpressVPN Router version 1 allows remote attackers to obtain sensitive information when the server running as reverse proxy via specially crafted request. | high |
| CVE-2023-45132 | NAXSI is an open-source maintenance web application firewall (WAF) for NGINX. An issue present starting in version 1.3 and prior to version 1.6 allows someone to bypass the WAF when a malicious `X-Forwarded-For` IP matches `IgnoreIP` `IgnoreCIDR` rules. This old code was arranged to allow older NGINX versions to also support `IgnoreIP` `IgnoreCIDR` when multiple reverse proxies were present. The issue is patched in version 1.6. As a workaround, do not set any `IgnoreIP` `IgnoreCIDR` for older versions. | critical |

| CVE-2019-12938 | The Roundcube component of Analogic Poste.io 2.1.6 uses .htaccess to protect the logs/ folder, which is effective with the Apache HTTP Server but is ineffective with nginx. Attackers can read logs via the webmail/logs/sendmail URI. | medium |
| CVE-2016-0742 | The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (invalid pointer dereference and worker process crash) via a crafted UDP DNS response. | high |
| CVE-2023-28846 | Unpoly is a JavaScript framework for server-side web applications. There is a possible Denial of Service (DoS) vulnerability in the `unpoly-rails` gem that implements the Unpoly server protocol for Rails applications. This issues affects Rails applications that operate as an upstream of a load balancer's that uses passive health checks. The `unpoly-rails` gem echoes the request URL as an `X-Up-Location` response header. By making a request with exceedingly long URLs (paths or query string), an attacker can cause unpoly-rails to write a exceedingly large response header. If the response header is too large to be parsed by a load balancer downstream of the Rails application, it may cause the load balancer to remove the upstream from a load balancing group. This causes that application instance to become unavailable until a configured timeout is reached or until an active healthcheck succeeds. This issue has been fixed and released as version 2.7.2.2 which is available via RubyGems and GitHub. Users unable to upgrade may: Configure your load balancer to use active health checks, e.g. by periodically requesting a route with a known response that indicates healthiness; Configure your load balancer so the maximum size of response headers is at least twice the maximum size of a URL; or instead of changing your server configuration you may also configure your Rails application to delete redundant `X-Up-Location` headers set by unpoly-rails. | high |
| CVE-2021-45967 | An issue was discovered in Pascom Cloud Phone System before 7.20.x. A configuration error between NGINX and a backend Tomcat server leads to a path traversal in the Tomcat server, exposing unintended endpoints. | critical |
| CVE-2017-8301 | LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx. | medium |
| CVE-2025-2787 | KNIME Business Hub is affected by the Ingress-nginx CVE-2025-1974 ( a.k.a IngressNightmare ) vulnerability which affects the ingress-nginx component. In the worst case a complete takeover of the Kubernetes cluster is possible. Since the affected component is only reachable from within the cluster, i.e. requires an authenticated user, the severity in the context of KNIME Business Hub is slightly lower. Besides applying the publicly known workarounds, we strongly recommend updating to one of the following versions of KNIME Business Hub: * 1.13.3 or above * 1.12.4 or above * 1.11.4 or above * 1.10.4 or above * | high |
| CVE-2020-5901 | In NGINX Controller 3.3.0-3.4.0, undisclosed API endpoints may allow for a reflected Cross Site Scripting (XSS) attack. If the victim user is logged in as admin this could result in a complete compromise of the system. | critical |
| CVE-2021-23055 | On version 2.x before 2.0.3 and 1.x before 1.12.3, the command line restriction that controls snippet use with NGINX Ingress Controller does not apply to Ingress objects. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | medium |
| CVE-2023-25803 | Roxy-WI is a Web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. Versions prior to 6.3.5.0 have a directory traversal vulnerability that allows the inclusion of server-side files. This issue is fixed in version 6.3.5.0. | high |
| CVE-2016-0747 | The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 does not properly limit CNAME resolution, which allows remote attackers to cause a denial of service (worker process resource consumption) via vectors related to arbitrary name resolution. | medium |
| CVE-2024-22200 | vantage6-UI is the User Interface for vantage6. The docker image used to run the UI leaks the nginx version. To mitigate the vulnerability, users can run the UI as an angular application. This vulnerability was patched in 4.2.0. | medium |
| CVE-2021-23017 | A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact. | high |
| CVE-2018-16845 | nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module. | medium |
| CVE-2019-7401 | NGINX Unit before 1.7.1 might allow an attacker to cause a heap-based buffer overflow in the router process with a specially crafted request. This may result in a denial of service (router process crash) or possibly have unspecified other impact. | critical |
| CVE-2018-11747 | Previously, Puppet Discovery was shipped with a default generated TLS certificate in the nginx container. In version 1.4.0, a unique certificate will be generated on installation or the user will be able to provide their own TLS certificate for ingress. | critical |
| CVE-2016-0746 | Use-after-free vulnerability in the resolver in nginx 0.6.18 through 1.8.0 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (worker process crash) or possibly have unspecified other impact via a crafted DNS response related to CNAME response processing. | critical |
| CVE-2021-40150 | The web server of the E1 Zoom camera through 3.0.0.716 discloses its configuration via the /conf/ directory that is mapped to a publicly accessible path. In this way an attacker can download the entire NGINX/FastCGI configurations by querying the /conf/nginx.conf or /conf/fastcgi.conf URI. | high |
