Description
The User Registration plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.3.2.1 via deserialization of untrusted input in the following functions: ur_get_user_extra_fields, user_registration_form_field. This allows subscriber-level attackers 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.
