Name of the Vulnerable Software and Affected Versions User Registration WordPress plugin versions prior to 2.0.2

Description The issue arises from the improper sanitization of the user registration profile pic url value when submitted via the "user registration update profile details" AJAX action. This could allow any authenticated user to perform Stored Cross-Site attacks when their profile is viewed.

Recommendations For versions prior to 2.0.2, update to version 2.0.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the user registration update profile details AJAX action to minimize the risk of exploitation. Avoid using the user registration profile pic url value in the affected AJAX action until the issue is resolved.
