Dokan <=3.7.19 - Authenticated(Shop Manager+) PHP Object Injection via create_dummy_vendor

The Dokan plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.7.19 via deserialization of untrusted input via the 'create_dummy_vendor' function called by the 'import' REST API endpoint. This allows authenticated attackers with Shop Manager privileges or above to inject a PHP Object. No POP chain is known 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.
