Kimai 2.56.0 and earlier versions contain an authenticated cross-site request forgery (CSRF) vulnerability in the timesheet stop and restart API endpoints. The application exposes state-changing operations via GET requests, which should be read-only, allowing attackers to trick logged-in users into triggering unauthorized timesheet state changes. This can stop running timesheets or restart historical ones without user consent, potentially corrupting time tracking data and affecting billing or auditing processes. The issue is fixed by removing the GET routes and limiting these operations to PATCH requests only.
