Expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime.\n\nAn authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of workflows, and execution of system-level operations.","published":"2026-01-27T15:15:57.000Z","lastModified":"2026-06-17T10:15:51.000Z","status":"Analyzed","sourceIdentifier":"reefs@jfrog.com","cvss":{"version":"3.1","score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-95"],"affected":["n8n/n8n"],"epss":{"score":0.20401,"percentile":0.97488,"date":"2026-10-30","history":[{"date":"2026-09-24","score":0.20683,"percentile":0.97444}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 20.4%, higher than 97% of all known CVEs.
