{"id":"CVE-2026-86079","aliases":["GHSA-f2cp-m7mv-8jpv"],"url":"https://o3.security/vulnerability/CVE-2026-86079","summary":"n8n: Path Injection in Elasticsearch and ElasticSecurity Nodes via Unencoded Identifiers","details":"n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Elasticsearch and ElasticSecurity nodes interpolated workflow-controlled index and document identifiers directly into REST request paths. An identifier containing path separators or dot segments could select another index or a cluster administration endpoint under the stored Elasticsearch credential. The affected request construction includes packages/nodes-base/nodes/Elastic/Elasticsearch/GenericFunctions.ts and the missing toPathSegment encoding. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.","published":"2026-09-08T21:26:28.296Z","modified":"2026-09-11T03:31:00.385015416Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"n8n","fixedVersion":"1.123.76"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.38.2"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.37.7"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@1.123.76"},{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@2.37.7"},{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@2.38.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86079.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-f2cp-m7mv-8jpv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86079"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T03:31:00.385015416Z"}}
