Description
n8n is an open source workflow automation platform. Prior to versions 1.118.0 and 2.4.0, a vulnerability in the Merge node's SQL Query mode allowed authenticated users with permission to create or modify workflows to write arbitrary files to the n8n server's filesystem potentially leading to remote code execution. This issue has been patched in versions 1.118.0 and 2.4.0.

Executive Summary

This vulnerability exists in the n8n workflow automation platform, specifically in the Merge node's SQL Query mode. Before versions 1.118.0 and 2.4.0, authenticated users who had permission to create or modify workflows could exploit this flaw to write arbitrary files to the server's filesystem. This could potentially allow an attacker to execute remote code on the server.

Impact Analysis

If exploited, this vulnerability could allow an attacker with certain permissions to write arbitrary files on the n8n server, which may lead to remote code execution. This means the attacker could potentially take control of the server, manipulate workflows, access sensitive data, or disrupt services.
