Details
A local file inclusion vulnerability exists in the JSON component of gradio-app/gradio version 4.25. The vulnerability arises from improper input validation in the postprocess() function within gradio/components/json_component.py, where a user-controlled string is parsed as JSON. If the parsed JSON object contains a path key, the specified file is moved to a temporary directory, making it possible to retrieve it later via the /file=.. endpoint. This issue is due to the processing_utils.move_files_to_cache() function traversing any object passed to it, looking for a dictionary with a path key, and then copying the specified file to a temporary directory. The vulnerability can be exploited by an attacker to read files on the remote system, posing a significant security risk.
