Technical details

The plugin fails to sanitize JavaScript stored in form button click action configurations, resulting in stored XSS (CWE-79). An authenticated attacker with author role or above can store arbitrary JavaScript that executes client-side in the context of any user interacting with the form. The vulnerability requires an attacker to have WordPress author privileges, and the malicious payload is triggered when users click a button in the form.
