Critical Remote Code Execution Vulnerabilities in n8n Workflow Automation Platform

A critical vulnerability, CVE-2025-68613, has been discovered in the n8n open-source workflow automation platform, allowing authenticated users with workflow creation or editing permissions to execute arbitrary system commands on the underlying server. This flaw, rated 9.9 on the CVSS scale, stems from improper sandboxing of JavaScript expressions within workflow definitions, enabling attackers to escape restrictions and gain system-level access. The vulnerability does not require administrative privileges, making it a significant risk in environments with multiple users or weak access controls, and could lead to full system compromise, data exfiltration, workflow sabotage, and lateral movement.

Another related vulnerability, CVE-2025-68668, also enables sandbox escape in n8n, turning workflows into potential attack vectors. Both vulnerabilities highlight the urgent need for organizations using n8n to review user permissions, apply available patches, and implement strong access controls to mitigate the risk of exploitation. While there is no current evidence of active exploitation, the ease of attack and the platform's popularity make immediate remediation essential.
