Technical details
A missing object-level authorization vulnerability exists in Kimai's Team API endpoints within `src/API/TeamController.php`. The endpoints incorrectly use the `#[IsGranted('edit_team')]` attribute instead of `#[IsGranted('edit', 'team')]`. This causes the Symfony `TeamVoter` to abstain from voting because it does not recognize the single-argument attribute, leaving authorization solely to the `RolePermissionVoter`. Consequently, any user with the global `edit_team` permission (such as a promoted `ROLE_TEAMLEAD`) can bypass ownership checks and modify membership, customer, project, and activity assignments for any team via the API. This issue is patched in version 2.54.0.
