Name of the Vulnerable Software and Affected Versions The Social Share, Social Login and Social Comments Plugin WordPress plugin versions prior to 7.13.30

Description The issue is related to a Reflected Cross-Site Scripting problem. It occurs because the urls parameter in the the champ sharing count AJAX action is not properly sanitized and escaped before being outputted in the response. This action is accessible to both unauthenticated and authenticated users.

Recommendations For versions prior to 7.13.30, update to version 7.13.30 or later to resolve the issue. As a temporary workaround, consider restricting access to the the champ sharing count AJAX action to minimize the risk of exploitation. Avoid using the urls parameter in the affected AJAX endpoint until the issue is resolved.
