{"id":"GHSA-2vx9-7wpg-88jq","summary":"n8n: Legacy ExecuteWorkflow Node Bypassed File Path Restrictions","details":"## Impact\nThe `ExecuteWorkflow` node's `localFile` source option read workflow files from disk without applying checks enforced by other file-reading nodes. An authenticated user with permission to create or modify workflows could supply an arbitrary file path via the REST API, bypassing the `N8N_RESTRICT_FILE_ACCESS_TO` restriction. This allowed the attacker to determine whether arbitrary files exist on the server host. Where the targeted path contained a valid workflow JSON file, the file could additionally be loaded and executed, potentially triggering actions on downstream systems connected to that workflow.\n\nThe `localFile` source option is hidden from the n8n UI since v1.2 but remains accessible via the REST API.\n\n## Patches\nThe issue has been fixed in n8n version 2.20.0 or 2.19.3. Users should upgrade to this version or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict workflow creation and editing permissions to fully trusted users only.\n- Restrict network access to the n8n REST API to trusted users only.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","aliases":["CVE-2026-56352"],"modified":"2026-07-16T03:56:43.129824446Z","published":"2026-05-19T15:55:43Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-22"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-05-19T15:55:43Z"},"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-2vx9-7wpg-88jq"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"}],"affected":[{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.19.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-2vx9-7wpg-88jq/GHSA-2vx9-7wpg-88jq.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
