Estado: ModificadaMedia (5.3)—💥 Exploit
The CachingResourceDownloadRewriteRule class in Jira Server and Jira Data Center before version 8.5.11, from 8.6.0 before 8.13.3, and from 8.14.0 before 8.15.0 allowed unauthenticated remote attackers to read arbitrary files within WEB-INF and META-INF directories via an incorrect path access check.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- Puntuación base: 5.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 24%
- Percentil entre todas las CVEs puntuadas: 98
- Fecha de la puntuación: 7/10/2026
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.
