{"id":"CVE-2026-84805","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-84805","generatedAt":"2026-10-28T08:37:07.546Z","title":"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.","description":"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.","published":"2026-09-02T12:17:17.000Z","lastModified":"2026-09-02T14:17:18.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":5.3,"severity":"MEDIUM","vector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00287,"percentile":0.21144,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.29%).
