CVE-2026-107207

Estado: AplazadaMedia (6.9)—

LMCache hasta la 0.5.5 contiene una vulnerabilidad de falsificación de solicitudes del lado del servidor (SSRF) en su servicio de monitorización frontend que permite a atacantes no autenticados eludir la lista de permitidos del proxy registrando hosts arbitrarios. Los atacantes pueden añadir entradas mediante POST /api/proxies y después usar /proxy o /proxy2 para alcanzar hosts internos, leer respuestas y manipular nodos o detener el heartbeat.

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.

SSRF sin autenticación (PR:N, UI:N) en servicio frontend; permite registrar hosts arbitrarios y acceder a recursos internos, manipular nodos o causar DoS deteniendo heartbeat.

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.
