Prior to 1.8.231, when limit_user_customer_visibility is enabled, the load_customer_info AJAX action performs a global lookup using an attacker-controlled customer email and checks only whether the agent can access a separately supplied mailbox. A non-admin agent can name an accessible mailbox and retrieve an unrelated customer's rendered profile without invoking CustomerPolicy::view().
