CVE-2025-63588
An unauthenticated reflected cross-site scripting vulnerability in the query handling of CMSimpleXH allows remote attackers to inject and execute arbitrary JavaScript in a victim's browser via a crafted request (e.g., a maliciously crafted POST login). Successful exploitation may lead to theft of session cookies, credential disclosure, or other client-side impacts.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N
- Puntuación base: 7.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.34%
- Percentil entre todas las CVEs puntuadas: 25
- Fecha de la puntuación: 6/10/2026
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).
