{"identifier":"CVE-2026-102986","cve":{"id":"CVE-2026-102986","description":"Plane is an open-source project management tool. In 1.3.1 and earlier, EntityAssetEndpoint at the public project asset endpoint /api/public/assets/v2/anchor/{anchor}/ requires authentication for write operations but does not verify workspace or project membership. An authenticated user who knows a published project's public DeployBoard.anchor can create FileAsset records in that project and soft-delete existing assets by identifier, allowing cross-workspace file injection, storage abuse, and data loss. The issue is fixed in version 1.4.0.","published":"2026-10-14T20:17:28.907000+00:00","modified":"2026-10-15T17:17:10.263000+00:00","status":"Deferred","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-639"],"references":[{"url":"https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/pull/9288","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-8688-h9x2-v83m","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-8688-h9x2-v83m","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:H","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-15T16:30:34.832787Z","id":"CVE-2026-102986","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:22:28.595021+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":0.00513,"percentile":0.43682,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-102986","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-102986","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-102986","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
