CVE-2026-103932 Nov 5, 2026 Source: Vendor
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. From 3.0.5 until 3.0.17, the PCRE2 implementation of @rxGlobal in src/utils/regex.cc converts pcre2_match match-limit errors into an ordinary no-match result instead of propagating a non-OK RegexResult. When attacker-controlled input exhausts SecPcreMatchLimit, rules that rely on MSC_PCRE_LIMITS_EXCEEDED or its TX compatibility indicator do not run, so a request that should be rejected
