Vulnerability from github – Published: 2026-04-14 00:31 – Updated: 2026-04-15 21:30

Details

Crypt::SecretBuffer versions before 0.019 for Perl is suseceptible to timing attacks.

For example, if Crypt::SecretBuffer was used to store and compare plaintext passwords, then discrepencies in timing could be used to guess the secret password.

Severity

7.5 (High)
