{"schema":"threatline.record/2","record":{"id":"CVE-2026-104969","aliases":["GHSA-22g9-9xfv-q3fr"],"summary":"Plane: Cross-Tenant Cycle Issue Hijack via IDOR","details":"Plane is an open-source project management tool. Prior to 1.4.0, the cycle-issues endpoint accepts issue UUIDs in the request body without validating that they belong to the caller's workspace. An authenticated user can add issues from any workspace to a cycle they control. If a victim issue is already assigned to a cycle, the operation removes it from the victim's cycle, causing a destructive cross-tenant write. This issue 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-2026-104969","source_modified_at":"2026-10-05T17:48:30.635Z","fetched_at":"2026-10-23T18:52:38.922436Z","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-22g9-9xfv-q3fr","source_modified_at":"2026-10-05T16:57:17Z","fetched_at":"2026-10-23T21:47:51.402276Z","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-22g9-9xfv-q3fr","source_modified_at":"2026-10-05T16:57:17Z","fetched_at":"2026-10-23T21:47:51.402276Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00268,"percentile":0.17919,"score_date":"2026-10-23"},"published_at":"2026-10-05T16:57:52.957Z","modified_at":"2026-10-05T17:48:30.635Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104969","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T17:48:30.635Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-22g9-9xfv-q3fr","fetched_at":"2026-10-23T21:47:51.402276Z","source_modified_at":"2026-10-05T16:57:17Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104969","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-22g9-9xfv-q3fr","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9269","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/81d9873d7f1cf1d1252ed53c12dd33696be73a89","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":"2026-10-05T17:47:06.863715Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T17:48:30.635Z","content_hash":"cd97aa2c3999d6d97e6435782e96cae7f167085c2dd4995f08220fadbba64c23"}}
