CVE-2025-68613

Name of the Vulnerable Software and Affected Versions n8n versions 0.211.0 through 1.120.3 n8n versions 1.121.0 through 1.121.0 n8n versions 1.122.0 (affected versions not specified)

Description An issue exists in the workflow expression evaluation system where expressions provided 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 can abuse this behavior to execute arbitrary code with the privileges of the n8n process, potentially leading to a full compromise of the instance, unauthorized access to sensitive data, and execution of system-level operations. Approximately 24,700 unpatched instances have been reported as reachable on the internet, and the flaw has been actively exploited by the Zerobot botnet.

Recommendations Update to versions 1.120.4, 1.121.1, or 1.122.0. Limit workflow creation and editing permissions to fully trusted users only. Deploy n8n in a hardened environment with restricted operating system privileges and network access.
