Vulnerability Description
CVE-2025-68613 is a critical (CVSS 9.9) remote code execution (RCE) vulnerability that allows an authenticated attacker 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 vulnerability exists in n8n’s 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. This allows authenticated attackers to execute arbitrary code.
