## Technical details

The plugin stores unsanitized user input from the message parameter in form data attributes without proper output escaping, allowing authenticated subscribers and above to inject JavaScript. The vulnerability is triggered when visitors access a listing page with an embedded form that displays the attacker's injected script payload. A fix adds htmlspecialchars() escaping with ENT_QUOTES and UTF-8 encoding to the message output.
