CVE-2026-87983

Estado: AplazadaCrítica (9.2)—

An arbitrary file read vulnerability in Mistral Vibe, introduced in version 2.6.0, allows an attacker to bypass workspace restrictions using quoted absolute paths in allowlisted shell commands. Improper handling of quotation marks during path validation enables files outside the active workspace to be read 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.

Acceso de red sin autenticación (AV:N, PR:N, UI:N) permite leer archivos arbitrarios fuera del workspace mediante bypass de validación de rutas (CWE-22). El atacante obtiene acceso a datos confidenciales sin interacción.

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.
