Mindstien Quick Login <= 1.0 - Unauthenticated Privilege Escalation via Account Takeover
The Mindstien Quick Login plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.0. This is due to the plugin not properly verifying a user's identity prior to authenticating them. This makes it possible for unauthenticated attackers to log in as other users, including administrators.
