Official description

The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions 6.0.0 to 6.0.6. This is due to the plugin accepting an arbitrary email address when a username is used in the password reset request. This makes it possible for unauthenticated attackers to send a password reset link for any user registered on the site to their own email address.

The underlying weakness: Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
