Name of the Vulnerable Software and Affected Versions
n8n versions 0.211.0 through 1.120.3

n8n versions 1.122.0 (affected versions not specified)
Description
A critical Remote Code Execution (RCE) issue exists in the workflow expression evaluation system. Authenticated users can provide expressions during workflow configuration that are evaluated in an execution context insufficiently isolated from the underlying runtime. This allows an attacker to execute arbitrary code with the privileges of the n8n process, potentially leading to full instance compromise, unauthorized sensitive data access, and system-level operations. Approximately 24,700 unpatched instances are publicly accessible worldwide, primarily in North America and Europe. The Zerobot botnet has been observed exploiting this flaw to hijack automated workflows for malicious command execution.
Recommendations
Upgrade 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.
