Name of the Vulnerable Software and Affected Versions Contest Gallery WordPress plugin versions prior to 19.1.5.1 Contest Gallery Pro WordPress plugin versions prior to 19.1.5.1

Description The issue arises from the failure to escape the user id POST parameter before it is concatenated to an SQL query in the ajax-functions-backend.php file. This may allow malicious users with at least author privilege to leak sensitive information from the site's database.

For Contest Gallery Pro WordPress plugin versions prior to 19.1.5.1, update to version 19.1.5.1 or later.
