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.

XSS almacenado (CWE-79) en notificaciones de YouTrack permite inyectar código JavaScript que se ejecuta en navegadores de otros usuarios. Requiere interacción del usuario para ver la notificación (AV:N, UI:R). Impacto: ejecución de scripts en cliente y potencial robo de credenciales/sesiones.

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.
