Nginx Open Source

CVE-2026-63030 is a critical unauthenticated remote code execution vulnerability affecting WordPress Core versions 6.9.0 through 6.9.4 and 7.0.0 through 7.0.1, allowing an unauthenticated attacker to execute arbitrary code via the WordPress REST API batch endpoint, potentially leading to complete website compromise.

A heap buffer overflow vulnerability, CVE-2026-42533, exists in NGINX Plus and NGINX Open Source when a 'map' directive uses regex matching and references its capture variables before the map's output variable or uses a non-cacheable variable under certain conditions, allowing an unauthenticated attacker to send crafted HTTP requests causing denial-of-service or remote code execution.

An injection vulnerability, CVE-2026-50107, exists in the NGINX configuration generator component of NGINX Gateway Fabric when configured with NGINX Plus or NGINX Open Source as the data plane, allowing authenticated attackers with CRD modification permissions to inject arbitrary NGINX configuration directives via unsanitized user-supplied string values in the access log format setting, leading to control plane compromise and potential defense evasion or system impact.

A vulnerability in Nginx allows a remote attacker to execute arbitrary code and cause a denial-of-service condition, affecting Nginx Open Source versions 1.x before 1.30.2, versions after 1.31.0 before 1.31.1, Nginx Plus versions 37.x before 37.0.1.1, and versions Rx before R36 P5 or R32 P7.

A remote, anonymous attacker can exploit a vulnerability in NGINX Open Source and NGINX Plus to perform a denial-of-service attack and potentially execute arbitrary code.

Multiple vulnerabilities in NGINX Open Source and NGINX Plus allow a remote, anonymous attacker to bypass security measures, execute arbitrary code, manipulate data, disclose confidential information, or cause a denial-of-service condition.

NGINX Plus and NGINX Open Source are vulnerable to a heap buffer overflow (CVE-2026-42945) due to crafted HTTP requests when the rewrite directive is followed by a rewrite, if, or set directive and an unnamed PCRE capture with a replacement string that includes a question mark, potentially leading to denial of service or code execution.

A buffer overflow vulnerability (CVE-2026-27654) exists in the ngx_http_dav_module of NGINX Open Source and NGINX Plus, potentially allowing attackers to terminate the NGINX worker process or modify files outside the document root by exploiting specific configurations with MOVE or COPY methods.
