A member with Editor access to a shared workflow (when workflow sharing is enabled) who knows a target credential's ID can reference that credential in the inline JSON; it passes save-time and runtime validation and resolves in the parent workflow's project context, allowing the attacker to use or exfiltrate credentials they are not permitted to access.","published":"2026-08-11T13:19:06.367","modified":"2026-08-11T13:19:06.367","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-cj9h-qx8g-pq2g"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/n8n-before-credential-exfiltration-via-sub-workflow"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-11T13:19:06.367"}}
