CVE-2026-107205
LMCache hasta la 0.5.5 contiene una vulnerabilidad de falta de autenticación en el coordinador multiproceso que permite a atacantes remotos no autenticados acceder a su API HTTP de control de la flota, que escucha por defecto en todas las interfaces. Los atacantes pueden registrar o dar de baja instancias mediante /instances, sobrescribir cuotas mediante los endpoints /quota, inyectar eventos mediante /events y enumerar /directory/keys para interrumpir el almacenamiento en caché y revelar metadatos de ubicación.
