## Description

The Dokan plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 5.3.1 via deserialization of untrusted input from the '_product_attributes' and '_default_attributes' product meta, which was passed through maybe_unserialize() after get_post_meta() had already unserialized it. This makes it possible for authenticated attackers with vendor-level access, which can typically be obtained through Dokan's front-end vendor registration, to inject a PHP Object when a product is saved or its edit/variations screen is rendered. No known POP chain is present in the vulnerable software; 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.
