CVE-2026-87988

Estado: AplazadaCrítica (10)—

An arbitrary file access vulnerability in Mistral Vibe allows an attacker to bypass workspace restrictions through commands classified as unconditionally allowed. Missing path validation for these commands enables access to files outside the active workspace without user approval.

CVSS

Probabilidad de explotación (EPSS)

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.

Vector AV:N/PR:N/UI:N indica acceso de red sin privilegios ni interacción. CWE-732 (permisos incorrectos) + falta de validación de rutas permite leer archivos fuera del workspace. T1005 (acceso a datos) y T1222 (cambio de permisos de archivos) por bypass de restricciones.

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.
