The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

NGINX Open Source before versions 1.23.2 and 1.22.1, NGINX Open Source Subscription before versions R2 P1 and R1 P1, and NGINX Plus before versions R27 P1 and R26 P1 have a vulnerability in the module ngx_http_mp4_module that might allow a local attacker to cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted audio or video file. The issue affects only NGINX products that are built with the module ngx_http_mp4_module, when the mp4 directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger processing of a specially crafted audio or video file with the module ngx_http_mp4_module.

NGINX Plus before versions R27 P1 and R26 P1 have a vulnerability in the module ngx_http_hls_module that might allow a local attacker to corrupt NGINX worker memory, resulting in its crash or potential other impact using a specially crafted audio or video file. The issue affects only NGINX Plus when the hls directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger processing of a specially crafted audio or video file with the module ngx_http_hls_module.

NGINX Open Source before versions 1.23.2 and 1.22.1, NGINX Open Source Subscription before versions R2 P1 and R1 P1, and NGINX Plus before versions R27 P1 and R26 P1 have a vulnerability in the module ngx_http_mp4_module that might allow a local attacker to corrupt NGINX worker memory, resulting in its termination or potential other impact using a specially crafted audio or video file. The issue affects only NGINX products that are built with the ngx_http_mp4_module, when the mp4 directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger processing of a specially crafted audio or video file with the module ngx_http_mp4_module.

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.

In versions 2.x before 2.3.0 and all versions of 1.x, An attacker authorized to create or update ingress objects can obtain the secrets available to the NGINX Ingress Controller. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

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.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A session fixation issue was discovered in the NGINX OpenID Connect reference implementation, where a nonce was not checked at login time. This flaw allows an attacker to fix a victim's session to an attacker-controlled account. As a result, although the attacker cannot log in as the victim, they can force the session to associate it with the attacker-controlled account, leading to potential misuse of the victim's session.
