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.
