The User Profile Builder WordPress plugin before 4.0.1 does not validate the type of data being deserialized when importing a configuration file, allowing high privilege users such as administrators to conduct PHP Object Injection. The affected feature is a free add-on which is disabled by default, and no POP chain is present in the User Profile Builder WordPress plugin before 4.0.1 itself, so further impact requires a suitable gadget from another installed User Profile Builder WordPress plugin before 4.0.1 or .
