## Description

The WP User Manager plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'directory-search' parameter of the user directory shortcode in all versions up to, and including, 2.10.3. This is due to the visitor-supplied wildcard search being passed to WP_User_Query without restricting the searched columns, so the search also matched user email addresses and login names. This makes it possible for unauthenticated attackers to enumerate or confirm registered users' email addresses by searching for partial email strings on a published user directory page.
