Themesflat Addons For Elementor <= 2.0.0 - Unauthenticated PHP Object Injection

The Themesflat Addons For Elementor plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.0.0 via deserialization of untrusted input through the 'settings' parameter retrieved from the tf_product_filter nopriv AJAX action. This allows unauthenticated attackers to inject a PHP Object. 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.
