Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
