Medium severity, CVSS 6.1. EPSS: 1.9% chance of exploitation in the next 30 days.

The Social Share, Social Login and Social Comments Plugin WordPress plugin before 7.13.30 does not sanitise and escape the urls parameter in its the_champ_sharing_count AJAX action (available to both unauthenticated and authenticated users) before outputting it back in the response, leading to a Reflected Cross-Site Scripting issue.
