NewCVE-2026-74846 (opens in a new tab)How to fix?
There is no fixed version for Debian:unstable libcatalyst-plugin-authentication-perl.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcatalyst-plugin-authentication-perl package and not the libcatalyst-plugin-authentication-perl package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
Catalyst::Plugin::Authentication versions before 0.10029 for Perl allow timing attacks on stored passwords via eq comparisons in the legacy password verifier.
CVE-2026-5091 was fixed in the realm-based verifier. The legacy verifier, used by the deprecated login method, compares clear-text passwords, crypt hashes and base64 digests with eq, so the comparison time depends on how many leading bytes match.
A remote attacker can use response-time differences to guess the stored password or hash.
