Advisory

Source description from Wordfence Intelligence, credited to Afan, moonge.

The 6Storage Rentals plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.28.0 This is due to the six_storage_create_wp_user() AJAX handler being registered on wp_ajax_nopriv_six_storage_create_wp_user without any nonce, capability, credential, or ownership verification, while calling wp_set_current_user() and wp_set_auth_cookie() for any WordPress user resolved by the attacker-supplied email address. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, by submitting that user's email address.
