Summary

The Form Builder CP WordPress plugin before version 1.2.47 does not properly sanitize a form configuration value before storing and using it in a client-side script. Authenticated users with Editor-level access and above can perform Stored Cross-Site Scripting attacks against any visitor of a page rendering the affected form, even when the `unfiltered_html` capability is disallowed (e.g., in a multisite network).

Risk Assessment

An attacker can inject a malicious script that executes in visitors' browsers, potentially leading to session theft, redirects, or data theft.

Recommendation

Update the Form Builder CP plugin to version 1.2.47 or later.
