Description
The All-In-One Security (AIOS) – Security and Firewall plugin for WordPress is vulnerable to two-factor authentication bypass via the WooCommerce 'Lost password' facility in all versions up to, and including, 5.4.10, due to the plugin not ending the session WooCommerce creates after a password reset for users who have two-factor authentication active. This makes it possible for unauthenticated attackers who can read the victim's email inbox to reset the account's password and be logged in without giving a two-factor authentication code. Exploitation requires WooCommerce to be active, in a version that logs the user in after a password reset.
