A value containing path separators or dot segments changed which endpoint the request actually reached, so an operation intended for one document could hit another index or a cluster administration endpoint instead, under the stored Elasticsearch credential. The patch encodes each identifier as a single URL path segment and rejects values that normalise away.\n\n## Patches\n\nThe issue has been fixed in n8n versions 1.123.76, 2.37.7, and 2.38.2. 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- Disable the affected nodes by adding `n8n-nodes-base.elasticsearch` and `n8n-nodes-base.elasticSecurity` to the `NODES_EXCLUDE` environment variable if they are not required.\n- Audit existing workflows that use these nodes and ensure that index and document identifier fields do not accept externally-controlled input.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-09-10T21:05:43+00:00","modifiedAt":"2026-09-10T21:15:05.057952+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.123.76"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.38.0"},{"kind":"fixed","version":"2.38.2"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.0.0"},{"kind":"fixed","version":"2.37.7"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-f2cp-m7mv-8jpv","https://nvd.nist.gov/vuln/detail/CVE-2026-86079","https://github.com/n8n-io/n8n","https://github.com/n8n-io/n8n/releases/tag/n8n@1.123.76","https://github.com/n8n-io/n8n/releases/tag/n8n@2.37.7","https://github.com/n8n-io/n8n/releases/tag/n8n@2.38.2"],"sourceUrl":"https://github.com/advisories/GHSA-f2cp-m7mv-8jpv","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-f2cp-m7mv-8jpv","identifiers":["GHSA-f2cp-m7mv-8jpv","CVE-2026-86079"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
