CVE-2026-9641

CVE-2026-9641 affects Crypt::PBKDF2 for Perl prior to 0.261630. The vulnerability stems from a weak default configuration: using HMAC-SHA1 as the default algorithm and a default 1000 iterations, which is insufficient for modern password hashing. The impact, per sources, could involve reduced resi...
