CVE-2025-40645Network attack vector

Unauthenticated customer-data disclosure via phone lookup

Published Oct 2, 2025 · Updated Oct 2, 2025

Information disclosure in ViDay allows remote attackers to obtain sensitive customer data through an unauthenticated phone lookup request. The /api/reserva/web/clients endpoint accepts an HTTP GET phone parameter and returns associated customer information without requiring authentication. Network access is the only reported gate, and the published impact is limited to customer-information disclosure, with no integrity or availability effect.
