Bottom line: n8n instances can be compromised through account takeover and sandbox escape.
The workflow automation tool n8n is vulnerable to multiple security flaws through which attackers can take over user accounts and bypass sandbox mechanisms.
n8n is a widely used workflow automation tool deployed in enterprise environments for integrating and automating business processes. The tool is vulnerable to multiple security flaws that allow attackers to penetrate running instances.
The vulnerabilities enable two critical attack scenarios: On one hand, user account data can be compromised and accounts taken over. On the other hand, escape from the sandbox environment is possible, which would grant attackers access to the underlying system. This is particularly critical because n8n is frequently used for automating sensitive processes and receives access to various backend systems and APIs.
The vendor has provided security updates. CISOs should prioritize identifying affected n8n instances, verify their version numbers, and deploy available patches promptly. At the same time, access logs should be reviewed to determine whether the vulnerabilities have already been exploited.
