Description
The Paytium: Mollie payment forms & donations plugin for WordPress is vulnerable to PHP Object Injection via the pt_form_field payment form parameters (checkbox fields and the pt-uploaded-files key) in all versions up to, and including, 5.0.5, due to deserialization of untrusted input with maybe_unserialize() without restricting allowed classes. This makes it possible for unauthenticated attackers to inject a PHP object. No known POP chain is present in the plugin itself. If a POP chain is present through another plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
