In version 2.38.0, a Denial of Service (DoS) vulnerability exists in the file processing logic when reading a file on endpoint `Filebrowser-Server-IP:PORT/files/{file-name}` . While the server correctly handles and stores uploaded files, it attempts to load the entire content into memory during read operations without size checks or resource limits. This allows an authenticated user to upload a large file and trigger uncontrolled memory consumption on read, potentially crashing the server and making it unresponsive. As of time of publication, no known patches are available."}, {"lang": "es", "value": "File Browser proporciona una interfaz de gesti\u00f3n de archivos dentro de un directorio espec\u00edfico y permite cargar, eliminar, previsualizar, renombrar y editar archivos.

Si bien el servidor gestiona y almacena correctamente los archivos cargados, intenta cargar todo el contenido en memoria durante las operaciones de lectura sin verificar el tama\u00f1o ni los l\u00edmites de recursos. Esto permite que un usuario autenticado cargue un archivo grande y provoque un consumo de memoria descontrolado durante la lectura, lo que podr\u00eda provocar un bloqueo del servidor y dejarlo inoperante. Al momento de la publicaci\u00f3n, no se conocen parches disponibles.
