What the vulnerability does

01Description

The Database Backup for WordPress plugin for WordPress is vulnerable to unauthorized database export in all versions up to, and including, 2.5.2.

Note: This vulnerability is only exploitable in WordPress Multisite environments where the deprecated is_site_admin() function exists.
