MEDIUM
Gradio Allows Unauthorized File Copy via Path Manipulation
Record summary
CVE-2025-48889 has a selected CVSS score of 5.3 (medium).
Description
Gradio is an open-source Python package that allows quick building of demos and web application for machine learning models, API, or any arbitrary Python function. Prior to version 5.31.0, an arbitrary file copy vulnerability in Gradio's flagging feature allows unauthenticated attackers to copy any readable file from the server's filesystem. While attackers can't read these copied files, they can cause DoS by copying large files (like /dev/urandom) to fill disk space. This issue has been patched in version 5.31.0.
