CVE-2026-9692

EUVD-2026-37926
Mojolicious::Sessions::Storable versions through 0.05 for Perl generate session ids insecurely.

The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, the heap address of an anonymous hash, and the PID.

These are predictable or low-entropy sources that are unsuitable for security purposes.
