Vulnerability Title
MyHome Core <= 4.4.5 - Authentication Bypass to Account Takeover via Activation Token
Source: CVE Program / CVE List V5
Vulnerability Description
The MyHome Core plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 4.4.5. This is due to missing authorization in the send_link() AJAX handler and improper token validation in the activate() function. This makes it possible for unauthenticated attackers to generate an activation token for an unconfirmed user account and obtain a valid authentication cookie for that account, including administrators. Successful exploitation requires the MyHome theme to be configured in legacy/WPBakery mode with frontend registration and confirmation email enabled, and the target account must not already have the myhome_agent_confirmed user meta set.
