{"id":"GHSA-jv9x-w4gm-hwcm","summary":"Kimai has Missing Object-Level Authorization in the Team API","details":"### Summary\nThe Team API endpoints use #[IsGranted('edit_team')] instead of #[IsGranted('edit', 'team')], causing Symfony TeamVoter to abstain from voting. This removes entity-level ownership checks on team operations, allowing any user with the edit_team permission to modify any team, not just teams they are authorized to manage.\n\n### Details\nAll 8 team association endpoints in src/API/TeamController.php (lines 177, 201, 229, 252, 275, 298, 321, 339) use #[IsGranted('edit_team')] with a single argument. The web controller at src/Controller/TeamController.php:118 correctly uses #[IsGranted('edit', 'team')] with two arguments, passing the $team parameter as the subject.\nWhen edit_team is passed as the attribute, TeamVoter::supportsAttribute() returns false because it only recognizes view, edit, and delete. The voter abstains entirely. Only RolePermissionVoter fires, which checks the role-level permission without any entity-level ownership validation.\n\n### PoC\n#### Authenticate as a user with edit_team permission who is NOT a member of Team 1\n```\ncurl -X POST https://TARGET/api/teams/1/members/2 \\\n  -H \"Authorization: Bearer \u003cAPI_TOKEN\u003e\" \\\n  -H \"Content-Type: application/json\"\n```\n\n#### Expected: 403 Forbidden (user is not ROLE_ADMIN/ROLE_SUPER_ADMIN, or member of Team 1)\n#### Actual (pre-2.54.0): 200 OK, user added to Team 1\n\n### Impact\nIn default configuration, only ROLE_ADMIN and ROLE_SUPER_ADMIN have edit_team, and both roles already have irrevocable view_all_data access, making the missing check redundant. The vulnerability becomes exploitable if an administrator grants edit_team to a lower-privilege role (such as ROLE_TEAMLEAD) through the permissions UI. In that scenario, the lower-privilege user could modify any team's membership, customer assignments, project assignments, and activity assignments without being a member or teamlead of that team.","aliases":["CVE-2026-41498"],"modified":"2026-05-12T17:09:38.995037Z","published":"2026-04-24T16:17:35Z","database_specific":{"github_reviewed_at":"2026-04-24T16:17:35Z","nvd_published_at":"2026-05-08T04:16:14Z","cwe_ids":["CWE-862"],"severity":"LOW","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/kimai/kimai/security/advisories/GHSA-jv9x-w4gm-hwcm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41498"},{"type":"PACKAGE","url":"https://github.com/kimai/kimai"},{"type":"WEB","url":"https://github.com/kimai/kimai/releases/tag/2.54.0"}],"affected":[{"package":{"name":"kimai/kimai","ecosystem":"Packagist","purl":"pkg:composer/kimai/kimai"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.54.0"}]}],"versions":["0.1","0.2","0.3","0.4","0.5","0.6","0.6.1","0.7","0.8","0.8.1","0.9","1.0","1.0.1","1.1","1.10","1.10.1","1.10.2","1.11","1.11.1","1.12","1.13","1.14","1.14.1","1.14.2","1.14.3","1.15","1.15.1","1.15.2","1.15.3","1.15.4","1.15.5","1.15.6","1.16","1.16.1","1.16.10","1.16.2","1.16.3","1.16.4","1.16.5","1.16.6","1.16.7","1.16.8","1.16.9","1.17","1.17.1","1.18","1.18.1","1.18.2","1.19","1.19.1","1.19.2","1.19.3","1.19.4","1.19.5","1.19.6","1.19.7","1.2","1.20","1.20.1","1.20.2","1.20.3","1.20.4","1.21.0","1.22.0","1.22.1","1.23.0","1.23.1","1.24.0","1.25.0","1.26.0","1.27.0","1.28.0","1.28.1","1.29.0","1.29.1","1.3","1.30.0","1.30.1","1.30.10","1.30.11","1.30.2","1.30.3","1.30.4","1.30.5","1.30.6","1.30.7","1.30.8","1.30.9","1.4","1.4.1","1.4.2","1.5","1.6","1.6.1","1.6.2","1.7","1.8","1.9","2.0.0","2.0.0-alpha","2.0.0-beta","2.0.0-beta-2","2.0.0-beta-3","2.0.0-rc-1","2.0.1","2.0.10","2.0.11","2.0.12","2.0.13","2.0.14","2.0.15","2.0.16","2.0.17","2.0.18","2.0.19","2.0.2","2.0.20","2.0.21","2.0.22","2.0.23","2.0.24","2.0.25","2.0.26","2.0.27","2.0.28","2.0.29","2.0.3","2.0.30","2.0.31","2.0.32","2.0.33","2.0.34","2.0.35","2.0.4","2.0.5","2.0.6","2.0.7","2.0.8","2.0.9","2.1.0","2.10.0","2.11.0","2.12.0","2.13.0","2.14.0","2.15.0","2.16.0","2.16.1","2.17.0","2.18.0","2.19.0","2.19.1","2.2.0","2.2.1","2.20.0","2.20.1","2.21.0","2.22.0","2.23.0","2.24.0","2.25.0","2.26.0","2.27.0","2.28.0","2.29.0","2.3.0","2.30.0","2.31.0","2.32.0","2.33.0","2.34.0","2.35.0","2.35.1","2.36.0","2.36.1","2.37.0","2.38.0","2.39.0","2.4.0","2.4.1","2.40.0","2.41.0","2.42.0","2.43.0","2.44.0","2.45.0","2.46.0","2.47.0","2.48.0","2.49.0","2.5.0","2.50.0","2.51.0","2.52.0","2.53.0","2.6.0","2.7.0","2.8.0","2.9.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-jv9x-w4gm-hwcm/GHSA-jv9x-w4gm-hwcm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N"}]}
