Advisory

Source description from Wordfence Intelligence, credited to Yorick Koster,.

The Ecwid Ecommerce Shopping Cart plugin for WordPress is vulnerable to PHP Object Injection in versions before 4.4.4 via deserialization of untrusted input from the vulnerable cookie parameter 'ecwid_oauth_state' in the _load_state function. This allows unauthenticated attackers to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
