Executive Summary

This vulnerability affects the n8n workflow automation platform. Before certain patched versions, an authenticated user with permission to create or modify workflows could exploit a flaw in the XML Node to perform global prototype pollution. Prototype pollution is a type of attack that manipulates the prototype of a base object, potentially altering the behavior of the application. In this case, when combined with other nodes that also exploit prototype pollution, it could lead to remote code execution (RCE), allowing an attacker to execute arbitrary code on the system.

Impact Analysis

The vulnerability can have severe impacts because it allows an authenticated user with workflow creation or modification permissions to achieve remote code execution on the system. This means an attacker could potentially take full control of the affected system, execute arbitrary commands, manipulate workflows, access sensitive data, or disrupt services.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade n8n to one of the patched versions: 1.123.32, 2.17.4, or 2.18.1.

This vulnerability affects versions prior to these releases and involves an authenticated user with permission to create or modify workflows exploiting global prototype pollution via the XML Node.

Applying the update will prevent the prototype pollution and potential remote code execution.
