CyberRota Analysis

AI-Generated

n8n versions prior to 1.123.64, 2.x before 2.29.8, and before 2.30.1 are vulnerable to a DOM-based cross-site scripting flaw in the HTML preview feature, which lacks a sandbox attribute in the iframe srcdoc. This vulnerability allows an attacker with global:member privileges to execute injected scripts that can access authenticated APIs using the victim's session when the preview is opened. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized access and data exposure.

Original NVD Description

n8n before 1.123.64, 2.x before 2.29.8, and before 2.30.1 contains a DOM-based cross-site scripting vulnerability in the HTML preview, which renders execution output into an iframe srcdoc without the sandbox attribute. A sanitizer bypass allows injected script to execute same-origin as the editor. When a victim opens the preview, the script can call authenticated APIs using the victim's session. An account with global:member privileges can exploit the issue.
