Description OSIDB Bzimport 2025-04-15 07:39:05 UTC

On sites with Multi-Factor Authentication enabled, it was possible for a user to access some of their data  after passing only the first login factor (such as passing a username/password check). The user should have to also pass a second factor check before gaining access to that data.

Versions affected: 4.5 to 4.5.3, 4.4 to 4.4.7 and 4.3 to 4.3.11
Versions fixed:    4.5.4, 4.4.8 and 4.3.12
