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, 5.3.4, due to the plugin accepting any user-supplied 'target_email' value without checking that it belongs to an agent, agency or property contact, and using the user-supplied sender name and email in the From header. This makes it possible for unauthenticated attackers to make the site send emails with attacker-controlled content and a spoofed sender to arbitrary recipients.
