Detailsinfo

A vulnerability classified as critical was found in n8n up to 1.123.16/2.4.4/2.5.0. This vulnerability affects an unknown function of the component Workflow Expression Evaluation System. The manipulation with an unknown input leads to a eval injection vulnerability. The CWE definition for the vulnerability is CWE-95. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-1470 since 01/27/2026. The exploitation appears to be easy. The attack can be initiated remotely. There are neither technical details nor an exploit publicly available.
