Catalyst::Plugin::Authentication versions before 0.10029 for Perl allow
timing attacks on stored passwords via eq comparisons in the legacy
password verifier

Description
-----------
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.

Problem types
-------------
- CWE-208 Observable Timing Discrepancy

Solutions
---------
Upgrade to Catalyst-Plugin-Authentication 0.10029 or later.
