CVE-2026-9641

Estado: AplazadaMedia (5.3)—

Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations.

The default algorithm is HMAC-SHA1, which should only be used for legacy systems.

These versions default to using 1000 iterations.

Depending on the chosen algorithm, 220,000 to 1,400,000 iterations should be used.
