CVE-2026-19878

Estado: AnalizadaMedia (6.5)—

IBM Security Verify Access 10.0 hasta la 10.0.9.2 e IBM Verify Identity Access 11.0 hasta la 11.0.3 podrían permitir a un atacante remoto autenticado eludir pasos adicionales del flujo de autenticación.

Traducción automática del texto original de NVD (en inglés).

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.

Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N sugiere acceso remoto sin privilegios previos (T1190). El bypass de autenticación adicional permite eludir controles de acceso (T1078), impactando identidad y acceso.

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.
