urwid: Urwid: Predictable session IDs lead to remote code execution and information disclosure

A flaw was found in the urwid web display backend. This vulnerability arises from the use of a cryptographically insecure pseudo-random number generator PRNG for web session identifiers, making them predictable. An attacker could either observe enough session IDs to reconstruct the PRNG state or,...

GHSA-W67G-5RQW-F597 Gorilla WebSocket Uses Cryptographically Weak PRNG for WebSocket Mask Key

gorilla/websocket used math/rand cryptographically weak pseudo-random number generator to generate WebSocket frame mask keys prior to commit d67f4185. WebSocket masking keys MUST be unpredictable to prevent frame content injection attacks. math/rand produces deterministic output when seeded with ...
