Description

The Easy Username Updater plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.3. This is due to missing nonce validation on the eup_user_update function. This makes it possible for unauthenticated attackers to change arbitrary usernames via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
