Critical Vulnerabilities in n8n Allow Evasion of Protections

Several vulnerabilities have recently been discovered in the workflow automation tool n8n, which could allow attackers to compromise servers, steal credentials, and silently disrupt AI-driven business processes. These security issues persist despite the release of a patch in December, designed to address a serious expression vulnerability.

The ability of an attacker to bypass existing protections, even after the application of a specific patch, raises significant concerns about the overall security posture of n8n and the effectiveness of its mitigation mechanisms.

General Context on the Security of Automation Tools

Workflow automation tools, such as n8n, have become increasingly popular for simplifying and automating complex processes. However, their increasing adoption also makes them an attractive target for cyber attacks. Vulnerabilities in these tools can have serious consequences, allowing attackers to access sensitive data, disrupt business operations, and even compromise the entire IT infrastructure.
