CVE-2026-56599
HCL BigFix Service Management is affected by an Insecure Cookie Attribute Configuration vulnerability, which could allow an attacker to exploit missing security attributes such as SameSite, HttpOnly, Secure, and restrictive Paths, enabling Cross-Site Request Forgery (CSRF), session hijacking via Cross-Site Scripting (XSS), and unauthorized access.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N
- Puntuación base: 2.2
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.06%
- Percentil entre todas las CVEs puntuadas: 0
- Fecha de la puntuación: 2/10/2026
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).
