CVE-2026-1470: Authenticated users can bypass the Expression sandbox mechanism to achieve full remote code execution on n8n’s main node.

Noroxi assessment

Priority: Plan (action score 45/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 20.4% (FIRST EPSS); higher than 97.4% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: www.npmjs.com n8n 1.123.17, 2.4.5, 2.5.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to www.npmjs.com n8n 1.123.17, 2.4.5, 2.5.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
