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.","categories":["Unclassified"],"product":"plane","vendor":"makeplane","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102986","source_modified_at":"2026-10-15T16:30:42.901Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"plane","vendor":"makeplane","versions":[{"status":"affected","version":"< 1.4.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-8688-h9x2-v83m","source_modified_at":"2026-09-30T15:03:23Z","fetched_at":"2026-10-23T19:58:35.668311Z","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-8688-h9x2-v83m","source_modified_at":"2026-09-30T15:03:23Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00424,"percentile":0.35682,"score_date":"2026-10-23"},"published_at":"2026-10-14T19:29:04.449Z","modified_at":"2026-10-15T16:30:42.901Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102986","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T16:30:42.901Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-8688-h9x2-v83m","fetched_at":"2026-10-23T19:58:35.668311Z","source_modified_at":"2026-09-30T15:03:23Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102986","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-8688-h9x2-v83m","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9288","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","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":"2026-10-15T16:30:34.832787Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T16:30:42.901Z","content_hash":"13b9b4045d2473ba8245e21382aa3613f4ef925c0e264e1ef17e073a523ae448"}}
