Description OSIDB Bzimport 2025-10-16 14:39:50 UTC

Authentication endpoints for the mobile client and auth_webservice allowed unlimited or insufficiently throttled password attempts. This could enable attackers to systematically guess passwords for known usernames.

Versions affected: 5.0 to 5.0.2, 4.5 to 4.5.6, 4.4 to 4.4.10, 4.1 to 4.1.20
and earlier unsupported versions
Versions fixed: 5.0.3, 4.5.7, 4.4.11 and 4.1.21
