CVE-2022-0321

Name of the Vulnerable Software and Affected Versions WP Voting Contest WordPress plugin versions prior to 3.0

Description The issue arises from the lack of sanitization and escaping of the post id parameter in the response via the "wpvc social share icons" AJAX action. This action is accessible to both unauthenticated and authenticated users, leading to a Reflected Cross-Site Scripting issue.

Recommendations For versions prior to 3.0, update to version 3.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the "wpvc social share icons" AJAX action to minimize the risk of exploitation. Avoid using the post id parameter in the affected AJAX endpoint until the issue is resolved.
