CVE-2026-77341

A flaw was found in cpp-httplib, a C++ HTTP/HTTPS library. This vulnerability allows a remote attacker to inject arbitrary HTTP headers or split HTTP responses by sending specially crafted data within chunked response trailer headers. The library fails to properly validate these headers, enabling...

CVE-2026-77358

A flaw was found in cpp-httplib. The TLS Transport Layer Security-enabled WebSocket client improperly frees a TLS session while the WebSocket connection is still active. This timing issue, which occurs during the normal shutdown of a secure WebSocket connection, leads to a use-after-free...
