CVE-2026-54104

Estado: Pendiente de análisisAlta (8.7)—

The U.S. Government Accountability Office (GAO) Electronic Protest Docketing System (EPDS) and Civilian Board of Contract Appeals (CBCA) Electronic Docketing System (EDS) trusts client-provided values for the 'epds_role_id' parameter without verification, allowing a remote, authenticated attacker to escalate their own privileges.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso remoto con privilegios (PR:L) a servicios GAO/CBCA sin verificación del parámetro 'epds_role_id', permitiendo escalada de privilegios sin interacción.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
