CVE-2026-1481Network attack vector

Unauthenticated database exfiltration via Id_usuario SQL injection

Published Jan 27, 2026 · Updated Jan 27, 2026

Out-of-band SQL injection in Quatuor Evaluación de Desempeño allows remote attackers to extract sensitive database data. The Id_usuario parameter at /evaluacion_objetivos_anyo_sig_ver_auto.aspx is incorporated into a database operation without neutralizing injected SQL, which triggers data exfiltration through an external channel rather than the HTTP response. The endpoint is reachable over the network without authentication or user interaction, and the reported consequence is indirect disclosure of stored information.
