CVE-2026-52819
Severity not reportedKimai is an open-source time tracking application.
Kimai is an open-source time tracking application. Prior to 2.57.0, the GET /api/timesheets list endpoint accepts user and users[] target identifiers from a caller with view_other_timesheet but does not apply access_user or verify that a ROLE_TEAMLEAD requester leads a team containing each target user. TimesheetController::cgetAction() adds the resolved users directly to the query while project and customer filtering still permits records on unscoped projects or projects sharing ordinary team membership, allowing a teamlead to retrieve another user's descriptions, timing data, tags, rate, and internalRate even though GET /api/timesheets/{id} would deny access through TimesheetVoter. This issue is fixed in version 2.57.0.
