Name of the Vulnerable Software and Affected Versions WordPress InviteBox Plugin versions up to and including 1.4.1

Description The WordPress InviteBox Plugin is affected by a Reflected Cross-Site Scripting issue. This is due to the message parameter in the ~/admin/admin.php file, which allows attackers to inject arbitrary web scripts.

Recommendations For versions up to and including 1.4.1, update to a version later than 1.4.1 to resolve the issue. As a temporary workaround, consider restricting access to the ~/admin/admin.php file to minimize the risk of exploitation. Avoid using the message parameter in the affected API endpoint until the issue is resolved.
