Local file inclusion in gradio

Description

A local file inclusion vulnerability exists in the JSON component of gradio-app/gradio and was discovered in 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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
