Severity ?
5.3 (Medium) - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N
CWE
  • CWE-352 - Cross-Site Request Forgery (CSRF)
Summary
Kimai is an open-source time tracking application. Prior to 2.58.0, TimesheetController exposes GET /api/timesheets/{id}/stop and GET /api/timesheets/{id}/restart, which reuse an authenticated browser session and perform state-changing operations through GET requests without a request-forgery defense. A remote attacker can cause a logged-in user to request either route from attacker-controlled content, stopping a running timesheet or restarting a historical entry to create and start a new timesheet without the user's consent. The unauthorized changes can corrupt time records, billing, reports, approvals, and audits. This issue is fixed in version 2.58.0.
