## Technical details

The Chat Help plugin for WordPress (versions up to 3.1.3) fails to implement proper authentication and authorization checks on its REST API endpoints, specifically /wp-json/chat-help/v1/leads and /wp-json/chat-help/v1/leads/{id}. This vulnerability (CWE-862) allows unauthenticated remote attackers to query these endpoints to extract sensitive lead data. Exposed information includes customer PII (names, emails, phone numbers), WhatsApp messages, geolocation data (IPs, coordinates, ISP), device fingerprints, and WordPress account metadata for logged-in users who interacted with the forms. A patch appears to be available in versions following 3.1.3.
