{"schema":"threatline.record/2","record":{"id":"CVE-2026-102985","aliases":["GHSA-25gg-cxm8-g7h9"],"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.","categories":["Unclassified"],"product":"plane","vendor":"makeplane","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102985","source_modified_at":"2026-10-20T02:05:06.225Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"plane","vendor":"makeplane","versions":[{"version":"< 1.4.0","status":"affected"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9","source_modified_at":"2026-09-30T14:40:21Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"ecosystem":"other","name":"makeplane/plane"},"range":"<= 1.3.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9","source_modified_at":"2026-09-30T14:40:21Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00277,"percentile":0.19121,"score_date":"2026-10-23"},"published_at":"2026-10-14T19:31:13.476Z","modified_at":"2026-10-20T02:05:06.225Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102985","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T02:05:06.225Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-09-30T14:40:21Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102985","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9367","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/dc9d80b2d2a499b967f0b541e083b283f463719f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-20T02:04:42.986238Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T02:05:06.225Z","content_hash":"836a7c6b19cbbc5d3ed9c241d307bea71d1c6ebcee100f1a967db8d1adf564d8"}}
