Technical details
The plugin fails to properly sanitize user-supplied input in form fields, allowing stored cross-site scripting (XSS) attacks through improper neutralization of script-related HTML tags. An unauthenticated attacker can submit a form containing malicious HTML/JavaScript that persists in the database and executes in the browsers of subsequent users who view the form or its submissions.
