Starter Templates by Kadence WP <= 1.2.16 - Authenticated (Admin+) PHP Object Injection

The Starter Templates by Kadence WP plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.2.16 via the 'import_customizer_options' function. This allows authenticated users with administratior-level capabilities 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.
