CVE-2026-107174

Estado: Pendiente de análisisMedia (6.4)—

Se ha encontrado un fallo en source-to-image. Al desempaquetar archivos comprimidos, la aplicación no sanea correctamente los enlaces simbólicos que apuntan a rutas de archivo absolutas. Un atacante que proporcione una imagen de builder maliciosa puede explotar esta vulnerabilidad incrustando enlaces que apunten fuera del directorio de extracción. Esto permite al atacante eludir los límites del sandbox, lo que podría provocar la divulgación no autorizada de información o la modificación de archivos en el sistema host.

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.

Vulnerabilidad en source-to-image que requiere acceso remoto (AV:N, PR:L) a servicio de construcción de imágenes. Impactos: lectura no autorizada (CWE-61, información disclosure) y modificación de archivos (file modification) mediante enlaces simbólicos maliciosos.

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.
