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,...
