{"id":"CVE-2026-102985","summary":"Plane: Any project member can modify (deactivate) other members' records","details":"Plane is an open-source project management tool. In 1.3.1 and earlier, ProjectMemberViewSet.partial_update places its authorization checks inside the role update branch, so a guest or member can omit role and change another ProjectMember record's is_active field, including deactivating a project administrator. ProjectMemberPreferenceEndpoint.patch separately trusts the member_id path value and lets a project member overwrite another member's preferences. These missing object-level authorization checks permit membership disruption and cross-member preference tampering. The vulnerability is fixed in 1.4.0.","aliases":["GHSA-25gg-cxm8-g7h9"],"modified":"2026-10-16T02:47:28.638775898Z","published":"2026-10-14T19:31:13.476Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102985.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-862"]},"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/2026/102xxx/CVE-2026-102985.json"},{"type":"ADVISORY","url":"https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102985"},{"type":"FIX","url":"https://github.com/makeplane/plane/commit/dc9d80b2d2a499b967f0b541e083b283f463719f"},{"type":"FIX","url":"https://github.com/makeplane/plane/pull/9367"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/makeplane/plane","events":[{"introduced":"0"},{"fixed":"dc9d80b2d2a499b967f0b541e083b283f463719f"},{"fixed":"917b23a6c16d93fc00cef67900eff2755e8b13f7"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"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-2026-102985.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:N/I:H/A:N"}]}
