Description

The WP Email Debug plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the WPMDBUG_handle_settings() function in versions 1.0 to 1.1.0. This makes it possible for unauthenticated attackers to enable debugging and send all emails to an attacker controlled address and then trigger a password reset for an administrator to gain access to an administrator account.
