## Description

The WP User Manager plugin for WordPress is vulnerable to Sensitive Information Exposure via public profile URLs in all versions up to, and including, 2.10.3. This is due to the wpum_get_profile_url() function building profile links from the user's login name or nickname even when that value is an email address. This makes it possible for unauthenticated attackers to obtain users' email addresses from profile links when the profile permalink structure is set to username or nickname and affected users have an email address as their login or nickname.
