Hi, The following vulnerability was published for cpp-httplib. CVE-2026-29076[0]: | cpp-httplib is a C++11 single-file header-only cross platform | HTTP/HTTPS library. Prior to version 0.37.0, cpp-httplib uses | std::regex (libstdc++) to parse RFC 5987 encoded filename* values in | multipart Content-Disposition headers. The regex engine in libstdc++ | implements backtracking via deep recursion, consuming one stack | frame per input character. An attacker can send a single HTTP POST | request with a crafted filename* parameter that causes uncontrolled | stack growth, resulting in a stack overflow (SIGSEGV) that crashes | the server process. This issue has been patched in version 0.37.0. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
