Kadence WooCommerce Email Designer <= 1.5.6 - PHP Object Injection

The Kadence WooCommerce Email Designer for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.5.6 via deserialization of untrusted input via the 'raw' parameter in the import_woomail function. This allows administrator-level attackers or higher to inject a PHP Object. No POP chain appears to be 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.
