How the CVE Works
The vulnerability (CVE-2025-1234) in Formie allows attackers to inject malicious JavaScript code into email notification previews. This occurs due to insufficient input sanitization in the email notification content editor. When an attacker with access to form notification settings inserts a crafted payload (e.g., <script>alert('XSS')</script>), the code executes when the preview is rendered in the admin panel. The vulnerability does not affect delivered emails, only the preview functionality. Attackers could exploit this to steal admin session cookies or perform actions on behalf of the victim.
