CVE-2026-107206

Estado: AplazadaAlta (8.8)—

LMCache hasta la 0.5.5 contiene una vulnerabilidad de falta de autenticación en el servidor HTTP del modo multiproceso que permite a atacantes remotos no autenticados acceder a endpoints de gestión que escuchan por defecto en todas las interfaces. Los atacantes pueden leer credenciales del entorno mediante GET /env y la configuración mediante GET /config, vaciar cachés, eliminar objetos de caché y modificar las cuotas de los inquilinos para expulsar los datos en caché de otros inquilinos.

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 remoto sin autenticación a endpoints de gestión en HTTP (AV:N, PR:N, UI:N) permite leer credenciales de entorno (GET /env) y configuración, modificando cuotas de tenants para eviccionar datos cacheados.

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.
