What the vulnerability does
01Description
The Integration for Pipedrive and Contact Form 7, WPForms, Elementor, Ninja Forms plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.2.3 via deserialization of untrusted input within the verify_field_val() function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain in the Contact Form 7 plugin, which is likely to be used alongside, allows attackers to delete arbitrary files, leading to a denial of service or remote code execution when the wp-config.php file is deleted.
