Customizer Export/Import <= 0.9.5 - Authenticated (Administrator+) PHP Object Injection

The Customizer Export/Import for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 0.9.5 via deserialization of untrusted input from an imported file. This allows administrator-level attackers 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.
