Official description

Kimai is an open-source time tracking application. Prior to version 2.54.0, the Team API endpoints use #[IsGranted('edit_team')] instead of #[IsGranted('edit', 'team')], causing Symfony TeamVoter to abstain from voting. This removes entity-level ownership checks on team operations, allowing any user with the edit_team permission to modify any team, not just teams they are authorized to manage. This issue has been patched in version 2.54.0.
