{"id":"CVE-2026-80202","summary":"Kimai before 2.56.0 Authorization Bypass via TimesheetVoter","details":"Kimai before 2.56.0 does not enforce team-membership checks in TimesheetVoter::voteOnAttribute(), which maps permissions only to own_timesheet or other_timesheet. 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.)","aliases":["GHSA-9g2q-w3w2-vf7q"],"modified":"2026-08-28T11:30:34.406644313Z","published":"2026-08-25T23:19:07.165Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80202.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80202.json"},{"type":"ADVISORY","url":"https://github.com/kimai/kimai/security/advisories/GHSA-9g2q-w3w2-vf7q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80202"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/kimai-before-2.56.0-authorization-bypass-via-timesheetvoter"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kimai/kimai","events":[{"introduced":"0"},{"fixed":"ebb54e9c0c5c6ae342bcff3bf63beebfda838cfd"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"2.56.0"}]}}],"versions":["2.55.0","2.54.0","2.53.0","2.52.0","2.51.0","2.50.0","2.49.0","2.48.0","2.47.0","2.46.0","2.45.0","2.44.0","2.43.0","2.42.0","2.41.0","2.40.0","2.39.0","2.38.0","2.37.0","2.36.1","2.36.0","2.35.1","2.35.0","2.34.0","2.33.0","2.32.0","2.31.0","2.30.0","2.29.0","2.28.0","2.27.0","2.26.0","2.25.0","2.24.0","2.23.0","2.22.0","2.21.0","2.20.1","2.20.0","2.19.1","2.19.0","2.18.0","2.17.0","2.16.1","2.16.0","2.15.0","2.14.0","2.13.0","2.12.0","2.11.0","2.10.0","2.9.0","2.8.0","2.7.0","2.6.0","2.5.0","2.4.1","2.4.0","2.3.0","2.2.1","2.2.0","2.1.0","2.0.35","2.0.34","2.0.33","2.0.32","2.0.31","2.0.30","2.0.29","2.0.28","2.0.27","2.0.26","2.0.25","2.0.24","2.0.23","2.0.22","2.0.21","2.0.20","2.0.19","2.0.18","2.0.17","2.0.16","2.0.15","2.0.14","2.0.13","2.0.12","2.0.11","2.0.10","2.0.9","2.0.8","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","2.0.0","2.0.0-rc-1","2.0.0-beta-3","2.0.0-beta-2","1.30.4","2.0.0-beta","2.0.0-alpha","1.30.1","1.30.0","1.29.1","1.29.0","1.28.1","1.28.0","1.27.0","1.26.0","1.25.0","1.24.0","1.23.1","1.23.0","1.22.1","1.22.0","1.21.0","1.20.4","1.20.3","1.20.2","1.20.1","1.20","1.19.7","1.19.6","1.19.5","1.19.4","1.19.3","1.19.2","1.19.1","1.19","1.18.2","1.18.1","1.18","1.17.1","1.17","1.16.10","1.16.9","1.16.8","1.16.7","1.16.6","1.16.5","1.16.4","1.16.3","1.16.2","1.16.1","1.16","1.15.6","1.15.5","1.15.4","1.15.3","1.15.2","1.15.1","1.15","1.14.3","1.14.2","1.14.1","1.14","1.13","1.12","1.11.1","1.11","1.10.2","1.10.1","1.10","1.9","1.8","1.7","1.6.2","1.6.1","1.6","1.5","1.4.2","1.4.1","1.4","1.3","1.2","1.1","1.0.1","1.0","0.9","0.8.1","0.8","0.7","0.6.1","0.6","0.5","0.4","0.3","0.2","0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80202.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
