CVSS
- Puntuación base
- 6.1
- Versión
- 3.1
- Vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días
- 14 %
- Percentil entre todas las CVEs puntuadas
- 97
- Fecha de la puntuación
- 29/10/2026
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).
Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
- Publicado en Exploit-DB · Moodle 3.6.1 - Persistent Cross-Site Scripting (XSS) (30/4/2021)
- Prueba de concepto en GitHub (no verificada) · Lista de pruebas de concepto en GitHub
