Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Overview github.com/gorilla/websocket is a Go implementation of the WebSocket protocol. Affected versions of this package are vulnerable to Use of Cryptographically Weak Pseudo-Random Number Generator PRNG via the newMaskKey function in conn.go. An attacker can predict or recover WebSocket frame...

CVE-2026-10099 XX-Net V5.16.6 WebSocket Frame Parsing Data Corruption via simple_http_server.py

XX-Net V5.16.6 contains a WebSocket frame parsing vulnerability in the WebSocketreceiveworker routine of simplehttpserver.py that allows attackers to cause corrupted application data by sending unmasked WebSocket frames. The server unconditionally reads 4 bytes as a masking key regardless of...

CVE-2026-10099

XX-Net version 5.16.6 is affected by a WebSocket frame parsing vulnerability in the WebSocket_receive_worker routine of simple_http_server.py. The issue arises because the server unconditionally reads 4 bytes as a masking key regardless of the MASK bit in the frame header, causing the first 4 byt...
