CVE-2026-42871Network attack vector

Database-detail disclosure via verbose endpoint errors

Published May 11, 2026 · Updated May 11, 2026

Information disclosure in LabReDeS WeGIA before 3.7.0 allows remote attackers to read database-related details through a web request. The atendido/familiar_docfamiliar.php endpoint returns an overly descriptive error response when accessed, exposing backend database and implementation details instead of a generic failure. No authentication or user interaction is required; the details support infrastructure mapping and targeted follow-on attacks, without reported data modification or service interruption.
