Upgrade gradio to version 6.15.0 or higher.
Overview
gradio is a Python library for easily interacting with trained machine learning models
Affected versions of this package are vulnerable to Session Fixation via /proxy reverse proxy requests. A malicious HF Space can hijack user sessions and gain unauthorized access to other users' authenticated contexts by injecting malicious cookies through a shared HTTP client used in the reverse proxy endpoint. This allows the attacker's cookies to be replayed in subsequent proxy requests to other legitimate targets, impacting all users of the same deployment.
