CVE-2026-26318

Estado: ModificadaAlta (8.8)—

systeminformation is a System and OS information library for node.js. Versions prior to 5.31.0 are vulnerable to command injection via unsanitized `locate` output in `versions()`. Version 5.31.0 fixes the issue.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 1.27%
Percentil entre todas las CVEs puntuadas: 69
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

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation75 %
Impacto principalT1059 Command and Scripting Interpreterexecution85 %

AV:L, PR:L, UI:N indica escalada local sin interacción. Command injection en `locate()` permite ejecución de comandos arbitrarios tras elevar privilegios.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
