{"identifier":"CVE-2026-102985","cve":{"id":"CVE-2026-102985","description":"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.","published":"2026-10-14T20:17:28.750000+00:00","modified":"2026-10-20T03:17:12.243000+00:00","status":"Deferred","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","cvss_version":"3.1","affected":[],"weaknesses":["CWE-862"],"references":[{"url":"https://github.com/makeplane/plane/commit/dc9d80b2d2a499b967f0b541e083b283f463719f","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/pull/9367","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-25gg-cxm8-g7h9","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-20T02:04:42.986238Z","id":"CVE-2026-102985","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:22:28.570357+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00337,"percentile":0.27022,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/makeplane/plane/commit/dc9d80b2d2a499b967f0b541e083b283f463719f","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-102985","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-102985","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-102985","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
