{"id":"CVE-2026-77068","aliases":["GHSA-6h4x-896x-fw5m"],"url":"https://o3.security/vulnerability/CVE-2026-77068","summary":"n8n before 2.34.1 Remote Code Execution via Path Traversal","details":"n8n before 2.33.4 and 2.34.x before 2.34.1 contain a remote code execution vulnerability in the @n8n/workflow-sdk node-schema loader used for MCP node-schema loading. The loader derives a node's schema module path directly from the attacker-supplied node type string without validating path-traversal sequences. An authenticated user with global:member privileges can reference malicious files via path traversal, causing code execution in the n8n main process.","published":"2026-08-20T11:21:04.945Z","modified":"2026-08-22T03:58:14.005076180Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77068.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-6h4x-896x-fw5m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77068"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/n8n-before-remote-code-execution-via-path-traversal"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-22T03:58:14.005076180Z"}}
