CVE-2026-59881

A flaw was found in AIOHTTP. The WebSocket client in AIOHTTP processes compressed data frames even when the compression mechanism, known as permessage-deflate, has not been properly negotiated. A malicious server can exploit this by sending specially crafted compressed frames. This can lead to...

CVE-2026-29035

A flaw was found in CivetWeb. An unauthenticated remote attacker could exploit a heap and stack buffer overflow vulnerability by sending specially crafted compressed WebSocket frames. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. The...
