DescriptionThe 140+ Widgets | Best Addons For Elementor – FREE for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.4.3.1 via deserialization of untrusted input in the 'export_content' function. This allows authenticated attackers, with contributor-level permissions and above, 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. Thanks, Francesco
