Technical details
The vulnerability exists in the get_instance_css function called via the [siteorigin_widget] shortcode handler, which bypasses the normal sanitization pipeline (update()/sanitize_field_input()) by calling $the_widget->widget() directly on attacker-supplied decoded JSON instance data. This allows path traversal through the widget's CSS processing to read arbitrary files on the server. The attack requires authenticated access at the contributor level or above.
