{"id":"CVE-2026-104961","summary":"Plane: WorkspaceOwnerPermission missing is_active check allows deactivated users to retain owner access","details":"Plane is an open-source project management tool. Prior to 1.4.0, WorkspaceOwnerPermission does not require is_active=True when checking whether a user is a workspace owner. A deactivated user can therefore remain authorized as the workspace owner and retain owner-level access. This issue is fixed in 1.4.0.","aliases":["GHSA-wjgv-cq7w-258v"],"modified":"2026-10-08T02:30:20.232839586Z","published":"2026-10-05T16:49:26.834Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104961.json"},"references":[{"type":"WEB","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104961.json"},{"type":"ADVISORY","url":"https://github.com/makeplane/plane/security/advisories/GHSA-wjgv-cq7w-258v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104961"},{"type":"FIX","url":"https://github.com/makeplane/plane/commit/6c9dbb50434d16ea00a00d1574723dfd0c3d2446"},{"type":"FIX","url":"https://github.com/makeplane/plane/pull/9290"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/makeplane/plane","events":[{"introduced":"0"},{"fixed":"6c9dbb50434d16ea00a00d1574723dfd0c3d2446"},{"fixed":"917b23a6c16d93fc00cef67900eff2755e8b13f7"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.4.0"}]}}],"versions":["v1.3.1","v1.3.0","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.28.0","v0.27.1","v0.27.0","v0.26.1","v0.26.0","v0.25.3","v0.25.2","v0.25.1","v0.25.0","v0.24.0","v0.23.1","v0.23.0","v0.22-dev","v0.21-dev","v0.20-dev","v0.19-dev","v0.18-dev","v0.17-dev","v0.16-dev","v0.15.4-dev","v0.15.3-hotfix","v0.15.2-dev","v0.15.1-dev","v0.15-dev","v0.14.2-dev","v0.14.1-dev","v0.14-dev","v0.13.2-dev","v0.13.1-dev","v0.13-dev","v0.12.2-dev","v0.12.1-dev","v0.12-dev","v0.11-dev","v0.10-dev","v0.9-dev","v0.8-dev","v0.7.1-dev","v0.7-dev","v0.6-dev","v0.5-dev","v0.4-dev","v0.3.1-dev","v0.1-dev"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-104961.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
