Profile Builder < 4.0.1 - Admin+ PHP Object Injection via Import/Export

Description

The plugin 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 plugin itself, so further impact requires a suitable gadget from another installed plugin or theme.
