CyberRota Analysis

AI-Generated

The Edit Fields (Set) node in n8n versions prior to 1.123.67, 2.31.5, and 2.32.1 is vulnerable to prototype pollution, enabling authenticated users to manipulate field names and corrupt a shared global in the Node.js process. This vulnerability can lead to a denial of service for all users by disrupting the request-authentication path, necessitating a restart of the affected instance to restore functionality. Organizations using these versions of n8n should prioritize immediate updates to mitigate the risk of service disruption.

Original NVD Description

n8n before 1.123.67, 2.31.5, and 2.32.1 contains a prototype pollution vulnerability in the Edit Fields (Set) node. The node assigns output fields via a dot-notation path setter without restricting the field name, allowing an authenticated user to name a field after an inherited built-in method path and corrupt a shared global in the main Node.js process. Because that global is used on the request-authentication path, the instance then fails every authenticated request, causing an instance-wide denial of service for all users until the process is restarted.
