BIT-nginx-2026-42533 — NGINX Map directive and Regex matching vulnerability

Affected: Bitnami: nginx

Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.

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

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.(CVE-2026-42533)

NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_ssi_module module. This vulnerability may exist when the Server-Side Includes (SSI), proxy_pass, and proxy_buffering off directives are configured. With this configuration, an unauthenticated attacker with man-in-the-middle (MITM) abi…

UBUNTU-CVE-2026-42533

Affected: Ubuntu:Pro:14.04:LTS: nginx, Ubuntu:Pro:16.04:LTS: nginx, Ubuntu:Pro:18.04:LTS: nginx, Ubuntu:Pro:20.04:LTS: nginx, Ubuntu:22.04:LTS: nginx, Ubuntu:24.04:LTS: nginx, Ubuntu:26.04:LTS: nginx

A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
