Description OSIDB Bzimport 2025-10-16 14:36:16 UTC

Certain login endpoints were improperly validated for MFA enforcement, allowing users with valid username and password combinations to log in without completing second-factor authentication. This exposes affected accounts to unauthorized access.

Versions affected: 5.0 to 5.0.2, 4.5 to 4.5.6 and 4.4 to 4.4.10
Versions fixed: 5.0.3, 4.5.7 and 4.4.11
