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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-52823)\n\nAffected packages:\n\n- `kimai/kimai <= 2.57.0`\n\nPatched in:\n\n- `kimai/kimai 2.58.0`\n\nSource: https://github.com/advisories/GHSA-r8vr-m544-qh4h","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":203572,"id":"CVE-2026-52823","ts":1789472201763,"field":"cvss","old":null,"new":"5.3"}]}
