Name of the Vulnerable Software and Affected Versions Visual Form Builder WordPress plugin versions prior to 3.0.4

Description The issue allows high privilege users, such as admins, to set Cross-Site Scripting payload in the Form Name, even when the unfiltered html capability is disallowed. This is due to the lack of sanitization or escaping of the Form Name.

Recommendations For versions prior to 3.0.4, update to version 3.0.4 or later to resolve the issue. As a temporary workaround, consider restricting the ability of high privilege users to set the Form Name until the update is applied.
