Disable Users <= 1.0.5 - Disabled Account Authorization Bypass
The Disable Users plugin for WordPress is vulnerable to protection mechanism failure in all versions up to, and including, 1.0.5. This is due to the plugin not properly restricting XMLRPC and Application Passwords for disabled accounts. This makes it possible for authenticated attackers, with subscriber-level access and above, to bypass disabled account restrictions.
