| CVE-2025-40926 | Plack::Middleware::Session::Simple versions before 0.05 for Perl generates session ids insecurely. The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predictable session ids could allow an attacker to gain access to systems. Plack | 9b29abf9-4ab0-4765-b253-1875cd9b441e | 9.8 | 0.43% | 2026-03-04 | 2026-06-17 |
