## Technical details

A sensitive information disclosure vulnerability exists in WeGIA versions prior to 3.7.0 due to improper error handling in the 'atendido/familiar_docfamiliar.php' component. The application returns overly verbose error messages that include database-related details and implementation specifics. An unauthenticated remote attacker can trigger these errors to leak information such as permitted file extensions, buffer sizes, or specific image processing libraries. This data facilitates reconnaissance and the development of targeted payloads to bypass security filters. The issue is addressed in version 3.7.0.
