Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | high | |
| CVE-2020-36309 | ngx_http_lua_module (aka lua-nginx-module) before 0.10.16 in OpenResty allows unsafe characters in an argument when using the API to mutate a URI, or a request or response header. | medium | |
| CVE-2026-27784 | The 32-bit implementation of NGINX Open Source has a vulnerability in the ngx_http_mp4_module module, which might allow an attacker to over-read or over-write NGINX worker memory resulting in its termination, using a specially crafted MP4 file. The issue only affects 32-bit NGINX Open Source if it is built with the ngx_http_mp4_module module and the mp4 directive is used in the configuration file. Additionally, the attack is possible only if an attacker can trigger the processing of a specially crafted MP4 file with the ngx_http_mp4_module module. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | high | |

| CVE-2022-41347 | An issue was discovered in Zimbra Collaboration (ZCS) 8.8.x and 9.x (e.g., 8.8.15). The Sudo configuration permits the zimbra user to execute the NGINX binary as root with arbitrary parameters. As part of its intended functionality, NGINX can load a user-defined configuration file, which includes plugins in the form of .so files, which also execute as root. | high | |
| CVE-2020-5867 | In versions prior to 3.3.0, the NGINX Controller Agent installer script 'install.sh' uses HTTP instead of HTTPS to check and install packages | high | |
| 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 | |

In affected versions a maliciously crafted request for static assets could cause error responses to be cached by Discourse's default NGINX proxy configuration. A corrected NGINX configuration is included in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability. | medium | |
| CVE-2026-28755 | NGINX Plus and NGINX Open Source have a vulnerability in the ngx_stream_ssl_module module due to the improper handling of revoked certificates when configured with the ssl_verify_client on and ssl_ocsp on directives, allowing the TLS handshake to succeed even after an OCSP check identifies the certificate as revoked. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | medium | |
