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.)","state":0,"publishedAt":"2026-08-25T23:19:07.165+00:00","modifiedAt":"2026-10-08T15:25:23.141+00:00","affected":[{"ecosystem":"Vendor product","name":"kimai","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"kimai\",\n                    \"product\": \"kimai\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.56.0\"\n                        },\n                        {\n                            \"version\": \"2.56.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:composer/kimai/kimai\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/kimai/kimai/security/advisories/GHSA-9g2q-w3w2-vf7q","https://www.vulncheck.com/advisories/kimai-before-2.56.0-authorization-bypass-via-timesheetvoter"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-80202","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-80202","identifiers":["CVE-2026-80202"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
