CVE-2025-15604: Perl Insecure Random Rand Into Hashcve-2025-15604-perl-insecure-random-rand-into-hash
Perl's built-in rand() is being fed into a cryptographic hash (SHA-1/SHA-256/SHA-512/MD5) to derive bytes. rand() is seeded with at most 32 bits and is not a CSPRNG, so hashing it (optionally with $$, Time::HiRes::time, or other low-entropy values) does not produce cryptographically strong output. This pattern produces predictable session IDs, CSRF tokens, a
