Descriptions

An issue was discovered in gradio-app/gradio, where the `/component_server` endpoint improperly allows the invocation of any method on a `Component` class with attacker-controlled arguments. Specifically, by exploiting the `move_resource_to_block_cache()` method of the `Block` class, an attacker can copy any file on the filesystem to a temporary directory and subsequently retrieve it. This vulnerability enables unauthorized local file read access, posing a significant risk especially when the application is exposed to the internet via `launch(share=True)`, thereby allowing remote attackers to read files on the host machine. Furthermore, gradio apps hosted on `huggingface.co` are also affected, potentially leading to the exposure of sensitive information such as API keys and credentials stored in environment variables.

Se descubrió un problema en gradio-app/gradio, donde el endpoint `/component_server` permite incorrectamente la invocación de cualquier método en una clase `Component` con argumentos controlados por el atacante. Específicamente, al explotar el método `move_resource_to_block_cache()` de la clase `Block`, un atacante puede copiar cualquier archivo en el sistema de archivos a un directorio temporal y posteriormente recuperarlo. Esta vulnerabilidad permite el acceso de lectura de archivos locales no autorizados, lo que representa un riesgo significativo, especialmente cuando la aplicación está expuesta a Internet a través de "launch(share=True)", lo que permite a atacantes remotos leer archivos en la máquina host. Además, las aplicaciones de gradio alojadas en `huggingface.co` también se ven afectadas, lo que podría provocar la exposición de información confidencial, como claves API y credenciales almacenadas en variables de entorno.
