Mojolicious::Sessions::Storable versions through 0.05 for Perl generate
session ids insecurely

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.

Problem types
-------------
- CWE-340 Generation of Predictable Numbers or Identifiers
- CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator

Workarounds
-----------
Apply the patch, which requires an upgrade to Mojolicious 9.46 or
later.
