Estado: AnalizadaAlta (8.4)—

In JetBrains WebStorm before 2026.2 arbitrary code execution was possible before granting project trust via the configured Node.js interpreter

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.4

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.19%
Percentil entre todas las CVEs puntuadas: 8
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 Interpreterexecution80 %
Impacto secundarioT1565.001 Stored Data Manipulationimpact60 %

AV:L sin UI:R indica escalada local (T1068). La ejecución arbitraria de código antes del trust del proyecto permite T1059. CWE-829 (vulnerabilidad en dependencias) sugiere manipulación de archivos/configuración (T1565.001).

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.
