CVE-2025-40924: Perl Weak Entropy Seed Generationcve-2025-40924-perl-weak-entropy-seed-generation

Generating session seeds or cryptographic tokens using weak sources of entropy like `time` and `rand` leads to highly predictable values. An attacker can brute-force or correlate these inputs to guess the final output, leading to session hijacking. Use a true CSPRNG (e.g., Crypt::SysRandom or Math::Random::Secure) instead.
