CVE-2026-52822 Details
Description
Kimai is an open-source time tracking application. Prior to 2.58.0, PATCH /api/timesheets/{id}/restart, PATCH /api/timesheets/{id}/duplicate, and the web duplicate workflow can derive a new record from an owned historical timesheet after the user's access to its project or activity has been revoked. TimesheetVoter evaluates the own-timesheet permission before current team access, and its canStart() logic validates object visibility but does not verify the user's current team access to the referenced project and activity. An old entry therefore acts as a persistent capability to create new time records under an unauthorized project and activity, corrupting budgets, statistics, reports, and invoices after an administrative revocation. This issue is fixed in version 2.58.0.
A vulnerability in Kimai, an open-source time tracking application, allows users to restart or duplicate historical timesheet entries under projects they no longer have access to. This issue affects Kimai versions prior to 2.58.0. The vulnerability arises because the application evaluates ownership of timesheets without considering current project access, enabling unauthorized time entries that can disrupt budgeting and reporting processes.
Users should update Kimai to version 2.58.0 or later, where this vulnerability has been fixed.
