CVE-2026-46527 cpp-httplib: Malicious `X-Forwarded-For` Under Trusted-Proxy Configuration Triggers Empty `vector::front()`, Leading to Undefined Behavior and Server Crash
cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.44.0, When the server has called Server::settrustedproxies with a non-empty trusted-proxy list, an attacker can send an HTTP request that includes an X-Forwarded-For header whose value parses to no valid ...
CVE-2026-45352
The CVE-2026-45352 issue affects cpp-httplib (header-only HTTP/HTTPS library). Before version 0.43.4, the ChunkedDecoder::read_payload routine parses the chunk-size in chunked Transfer-Encoding with std::strtoul(), which can silently accept a minus sign. This allows negative chunk sizes (e.g., "-...
CVE-2026-45352 cpp-httplib DoS: Negative chunk-size in chunked Transfer-Encoding
