Summary

Kimai is an open-source time tracking application. Prior to 2.57.0, PATCH /api/timesheets/{id} and POST /api/timesheets accept a user-controlled project identifier through TimesheetApiEditForm and FormTrait, and ProjectRepository::getQueryBuilderForFormType() places that identifier in an unconditional OR branch that bypasses the team access criteria. Any authenticated user with edit_own_timesheet can therefore assign an owned timesheet to a project outside the user's teams, persist unauthorized project attribution, and retrieve project and customer metadata through GET /api/timesheets/{id}?full=true. TimesheetTeamAccessValidator now checks changed project and activity associations against current team access. This issue is fixed in version 2.57.0.
