Users are recommended to upgrade to version 1.12.0, which fixes the issue.

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.

AV:N, PR:L, UI:N indica acceso remoto con privilegios mínimos (cliente autenticado), clasificado como T1210. La evasión del allowlist permite lectura de archivos fuera del directorio permitido (T1005) y potencialmente manipular configuración (T1565).

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.
