Prior to 1.4.0, ProjectBulkAssetEndpoint.post in apps/api/plane/app/views/asset/v2.py retrieves assets using id__in=asset_ids and workspace__slug=slug but does not constrain the query with project_id from the URL. A workspace Guest can provide asset UUIDs from another project in the same workspace and reassign their issue_id, comment_id, page_id, draft_issue_id, or project_id to an entity the attacker controls. Plane then treats the attacker's project as the new owner and provides a presigned download URL for the hijacked file. 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-2026-105637","source_modified_at":"2026-10-05T19:09:51.157Z","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-r2hw-fff3-pjwp","source_modified_at":"2026-10-05T18:03:14Z","fetched_at":"2026-10-23T19:00:29.328130Z","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-r2hw-fff3-pjwp","source_modified_at":"2026-10-05T18:03:14Z","fetched_at":"2026-10-23T19:00:29.328130Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":9.6,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00319,"percentile":0.23706,"score_date":"2026-10-23"},"published_at":"2026-10-05T18:04:02.780Z","modified_at":"2026-10-05T19:09:51.157Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105637","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T19:09:51.157Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-r2hw-fff3-pjwp","fetched_at":"2026-10-23T19:00:29.328130Z","source_modified_at":"2026-10-05T18:03:14Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105637","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-r2hw-fff3-pjwp","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9495","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/15e835710c7f938e0fae9c0ee77bb8162ff436a0","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":"total","assessed_at":"2026-10-05T19:09:42.896444Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T19:09:51.157Z","content_hash":"8151968aec8831abe4f1c36206566742bd2f2de1f97bb7e387d4a058f6b85ff9"}}
