Description
The Essential Real Estate plugin for WordPress is vulnerable to payment bypass via the ere_free_package_ajax AJAX action in all versions up to, and including, 5.3.4, due to the function not checking that the user-supplied 'package_id' refers to a published free package, or that the user has not already used their free package. This makes it possible for authenticated attackers, with Subscriber-level access and above, to activate paid listing packages without paying, and to reuse the free package as many times as they like.
