As a result, any authenticated user with ROLE_TEAMLEAD (or a role holding edit_other_timesheet/delete_other_timesheet) can read, modify, and permanently delete timesheets belonging to any user system-wide via the API, regardless of team membership. Timesheet IDs are sequential integers and trivially enumerable. ROLE_USER accounts are correctly restricted. (Note: the maintainers characterize this behavior as matching the documented permission model.)","published":"2026-08-26T05:18:27.980","modified":"2026-08-26T14:17:17.107","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/kimai/kimai/security/advisories/GHSA-9g2q-w3w2-vf7q"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/kimai-before-2.56.0-authorization-bypass-via-timesheetvoter"},{"type":"WEB","url":"https://github.com/kimai/kimai/security/advisories/GHSA-9g2q-w3w2-vf7q"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-26T14:17:17.107"}}
