Description

The iThemes Security plugin for WordPress is vulnerable to sensitive information disclosure in versions up to, and including 5.6.1, due to invalid username/password combinations returning different HTTP headers on response. This makes it possible for attackers to observe differences in responses to determine valid usernames on the site (username enumeration).
