GHSA-5xrp-6693-jjx9 · Severity: critical · Ecosystem: npm — n8n Unsafe Workflow Expression Evaluation Allows Remote Code Execution
n8n contains a critical Remote Code Execution (RCE) vulnerability in its workflow Expression evaluation system. Expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime. An 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.
Conclusion & alert: CVE-2026-1470 is rated High Exploit Risk (84.6/100): CVSS Critical severity, with medium exploitation likelihood (EPSS 2.27%). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
