{"schema":"threatline.record/2","record":{"id":"GHSA-8crx-5h96-q72q","aliases":["GHSA-8crx-5h96-q72q"],"summary":"Execute Sub-workflow `source: url` / `source: localFile` Bypasses Shared-Workflow Credential Guard","details":"## Impact\n\nWhen a workflow is shared for editing, n8n checks on save that the editor does not add credentials they may not use. The Execute Sub-workflow node can load its sub-workflow from a URL or a local file at run time, and the check never saw that content. An editor of a shared workflow can therefore have credentials of the workflow's project resolved by a sub-workflow they serve, and receive the decrypted values.\n\n## Patches\n\nThe issue has been fixed in n8n versions 1.123.85, 2.44.1, and 2.43.5. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\n\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict n8n instance access to fully trusted users only.\n- Audit shared workflows for Execute Sub-workflow nodes using `source: url` or `source: localFile` parameters and remove or restrict them.\n- Remove editor access from any users who are not fully trusted until the instance is patched.\n- Apply network-level controls to prevent the n8n process from reaching attacker-controlled infrastructure if outbound HTTP cannot be fully restricted.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","categories":["Frameworks"],"product":"n8n","vendor":"","ecosystem":null,"affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-8crx-5h96-q72q","source_modified_at":"2026-10-14T09:43:53Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"n8n"},"range":"< 1.123.85"},{"source":"GitHub Advisory Database","source_url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-8crx-5h96-q72q","source_modified_at":"2026-10-14T09:43:53Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"n8n"},"range":"< 2.44.1"},{"source":"GitHub Advisory Database","source_url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-8crx-5h96-q72q","source_modified_at":"2026-10-14T09:43:53Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"n8n"},"range":"< 2.43.5"}],"fixed_versions":[],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-14T09:43:53Z","modified_at":"2026-10-14T09:43:53Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-8crx-5h96-q72q","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-14T09:43:53Z"}],"sources":["GitHub Advisory Database"],"references":[],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-14T09:43:53Z","content_hash":"0927b05f0688ae9f1e3e62aaeb1ec27b22a345e6ef25bd58cde436166e28abba"}}
