n8n – CVE-2025-68613: Critical RCE Vulnerability
A critical vulnerability ( CVE-2025-68613 ) has been identified in n8n , the popular workflow automation tool. The flaw lies in the expression evaluation system, where user-supplied expressions can escape the sandbox and access Node.js internals. This leads to arbitrary code execution with a CVSS score of 9.9 (Critical) . n8n is an open source workflow automation platform. Versions starting with 0.211.0 and prior to 1.120.4, 1.121.1, and 1.122.0 contain a critical Remote Code Execution (RCE) vulnerability in their workflow expression evaluation system. Under certain conditions, 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,...
