Ado::Sessions through version 0.935 for Perl generates cryptographically weak session identifiers by seeding SHA-1 with the built-in rand function, system time, and process ID, allowing attackers to predict valid session IDs and hijack user sessions. The vulnerability affects unmaintained code no longer available on CPAN, though it remains on BackPAN. EPSS exploitation probability is minimal at 0.02%, and no public exploit code has been identified, but the automatable nature of session prediction and partial technical impact warrant assessment for legacy deployments.
