Ninja Forms Contact Form – The Drag and Drop Form Builder for WordPress <= 3.6.12 - Authenticated (Administrator+) PHP Objection Injection

The Ninja Forms Contact Form – The Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.6.12 via deserialization of untrusted input. This allows administrator-level attackers to inject a PHP Object. No POP chain is present in the vulnerable NinjaForms. 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.
