CVE-2026-3255 HTTP::Session2 versions before 1.12 for Perl may generate weak session ids using the rand() function

HTTP::Session2 versions before 1.12 for Perl for Perl may generate weak session ids using the rand function. The HTTP::Session2 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 epo...
