## Technical details

The vulnerability exists in the /wp-json/sowb/v1/widgets/previews REST endpoint where the 'theme' parameter in widgetData payloads is not properly validated. Attackers with contributor-level access can bypass field validation by sending a legacy top-level theme key alongside a non-empty columns array, allowing inclusion of arbitrary PHP files. The update_fields() function only processes declared form fields, failing to sanitize the malicious theme parameter.
