CVE-2026-41498: Kimai has Missing Object-Level Authorization in the Team API

April 24, 2026 (updated May 12, 2026)

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.
