Technical details
The vulnerability is a missing authorization check in the wpas_do_mr_deny_user() function. Unlike its counterpart wpas_do_mr_activate_user(), the deny function fails to enforce current_user_can('edit_users') or current_user_can('edit_user', $user_id) checks and relies solely on a nonce that is not scoped to the target user ID. This allows any authenticated user (subscriber-level or above) with knowledge of the nonce to set the mr_user_denied flag on arbitrary user accounts and trigger denial notification emails. The attack requires only an active user session and does not require the target user's authorization or knowledge.
