      "value": "JuiceFS through 1.3.1, fixed in commit a46979c, contains an authentication bypass vulnerability that allows unauthenticated remote attackers to access sensitive debug and metrics endpoints by exploiting improper handler registration on the shared http.DefaultServeMux. Attackers can request the /debug/pprof/cmdline endpoint to obtain the process command line containing metadata engine connection strings with database credentials, granting full read/write access to filesystem metadata, while other pprof handlers leak internal state and profiling handlers enable denial of service."

      "value": "JuiceFS hasta 1.3.1, corregido en el commit a46979c, contiene una vulnerabilidad de omisión de autenticación que permite a atacantes remotos no autenticados acceder a puntos finales sensibles de depuración y métricas explotando un registro de gestor incorrecto en el http.DefaultServeMux compartido. Los atacantes pueden solicitar el punto final /debug/pprof/cmdline para obtener la línea de comandos del proceso que contiene cadenas de conexión del motor de metadatos con credenciales de base de datos, otorgando acceso completo de lectura/escritura a los metadatos del sistema de archivos, mientras que otros gestores pprof filtran el estado interno y los gestores de perfilado permiten la denegación de servicio."
