CyberRota Analysis

AI-Generated

The Form Node in n8n versions prior to 1.123.24, 2.10.4, and 2.12.0 is vulnerable to cross-site scripting and open redirect attacks due to unsanitized HTML fields and lax iframe sandbox policies. This allows authenticated users with workflow creation permissions to execute stored XSS attacks or redirect users to malicious sites. Organizations using affected versions should prioritize patching to mitigate the risk of exploitation and protect their users from potential phishing attacks.

Original NVD Description

n8n before 1.123.24, 2.10.4, and 2.12.0 (across its 1.x and 2.x branches) contains cross-site scripting and open redirect vulnerabilities in the Form Node due to unsanitized HTML description fields and overly permissive iframe sandbox policies. Authenticated users with workflow creation permissions can inject malicious scripts or redirect parameters to perform stored XSS attacks or phishing redirects against end users.
