The Form Builder CP WordPress plugin before 1.2.47 does not properly sanitize a form configuration value before storing it and using it as part of a client-side script execution, allowing authenticated users with Editor-level access and above to 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).. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
