 "title": "Essential Real Estate <= 5.3.5 - Authenticated (Subscriber+) Arbitrary Email Sending via Contact Agent Form",
 "description": "The Essential Real Estate plugin for WordPress is vulnerable to arbitrary email sending via the contact agent form (ere_contact_agent_ajax AJAX action) in all versions up to, and including, 5.3.5, due to an incomplete fix. The recipient is still taken from the 'target_email' request parameter, and the check that it is a known contact address accepts addresses that users control without verification: the 'Other contact' email of any published property, agent email addresses, and the account email of property authors. Account emails can be set through registration or a front-end profile change with no confirmation from the address owner. This makes it possible for authenticated attackers, with subscriber-level access and above, to make any email address an accepted recipient, for example by publishing a property through the front-end form, and then use the site to send messages to that address.",
