The WPFunnels plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.5.18 via deserialization of untrusted input.

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.
