Estado: ModificadaAlta (7.5)—💥 Exploit

The CachingResourceDownloadRewriteRule class in Jira before version 7.13.4, and from version 8.0.0 before version 8.0.4, and from version 8.1.0 before version 8.1.1 allows remote attackers to access files in the Jira webroot under the META-INF directory via a lax path access check.

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).

💥 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.
