AI-suggested
Until a fix is available, users should consider implementing a more secure session ID generation mechanism that uses cryptographically secure random number generators. Avoid relying on the default session ID generator in affected versions.
Description
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.
