{"id":"CVE-2026-84805","summary":"Kimai 2.61.0 before 2.63.0 Authentication Bypass via API","details":"Kimai versions from 2.61.0 before 2.63.0 fail to disable admin-only work-contract preferences for low-privilege users in the PATCH /api/users/{id}/preferences endpoint. Although the web interface gates these employment-contract fields behind the contract_other_profile admin permission, the WorkContractPreferenceSubscriber (introduced in 2.61.0) registers the preferences as enabled without a permission check, so an authenticated regular user can use the API to modify their own admin-only work-contract data. The issue is fixed in 2.63.0 by applying the same permission check to the API endpoint.","aliases":["GHSA-5mpc-5cg2-g99r"],"modified":"2026-09-04T03:47:24.124280122Z","published":"2026-09-02T11:11:18.388Z","database_specific":{"cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/84xxx/CVE-2026-84805.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/84xxx/CVE-2026-84805.json"},{"type":"ADVISORY","url":"https://github.com/kimai/kimai/security/advisories/GHSA-5mpc-5cg2-g99r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-84805"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/kimai-2.61.0-before-2.63.0-authentication-bypass-via-api"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kimai/kimai","events":[{"introduced":"368a8e48efac4ea2d644b466a8b19eb2fd68d31f"},{"fixed":"2e1c9e48b437cce69dcd52d0083862237ce0b321"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"2.61.0"},{"fixed":"2.63.0"}]}}],"versions":["2.62.0","2.61.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-84805.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
