CVE-2026-107704

Estado: AplazadaCrítica (9.3)—

La gema de Ruby image_optimizer 1.3.0 hasta la 1.9.0 contiene una vulnerabilidad de inyección de comandos del sistema operativo en ImageOptimizer#identify_format que permite a los atacantes ejecutar comandos proporcionando una ruta de imagen manipulada cuando la opción identify está habilitada. Los atacantes que controlen la ruta, como el nombre de un archivo subido, pueden añadir metacaracteres de shell como ';' que se ejecutan mediante las comillas invertidas de Ruby con los privilegios del proceso de Ruby.

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 CVSS AV:N/AC:L/PR:N sin UI:R indica explotación remota sin interacción (T1190). CWE-78 y descripción explícita de 'OS command injection' con 'execute commands via Ruby backticks' confirman T1059 como impacto de ejecución de código.

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.
