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.","state":0,"publishedAt":"2026-10-14T19:31:13.476+00:00","modifiedAt":"2026-10-20T02:05:06.225+00:00","affected":[{"ecosystem":"Vendor product","name":"plane","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"makeplane\",\n                    \"product\": \"plane\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.4.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9","https://github.com/makeplane/plane/pull/9367","https://github.com/makeplane/plane/commit/dc9d80b2d2a499b967f0b541e083b283f463719f","https://github.com/makeplane/plane/releases/tag/v1.4.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102985","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102985","identifiers":["CVE-2026-102985"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
