CVE-2025-8355

Estado: AnalizadaAlta (7.5)—

In Xerox FreeFlow Core version 8.0.4, improper handling of XML input allows injection of external entities. An attacker can craft malicious XML containing references to internal URLs, this results in a Server-Side Request Forgery (SSRF).

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 8.64%
Percentil entre todas las CVEs puntuadas: 95
Fecha de la puntuación: 5/10/2026

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).

🎯 Técnicas ATT&CK
