CVE-2026-52819

CVE-2026-52819 · Kimai: Teamlead authorization bypass in GET /api/timesheets allows reading other users' timesheet records without being teamlead of the target

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
