What is CVE-2026-1470?
CVE-2026-1470 is a critical code injection vulnerability in N8n N8n, published on 27 Jan 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-95
