Description The issue is related to the failure of the system to properly invalidate personal access tokens when a user is deactivated. This allows deactivated users to maintain full system access by exploiting access token validation flaws via continued usage of previously issued tokens.

Recommendations For versions 10.7.x through 10.7.0, update to a version that properly invalidates personal access tokens upon user deactivation. For versions 10.6.x through 10.6.2, update to a version that properly invalidates personal access tokens upon user deactivation. For versions 10.5.x through 10.5.3, update to a version that properly invalidates personal access tokens upon user deactivation. For versions 9.11.x through 9.11.12, update to a version that properly invalidates personal access tokens upon user deactivation.
