CVE-2026-28414: Gradio absolute path traversal on Windows with Python 3.13+ file read

Summary

Gradio, an open-source Python package for prototyping, is affected before version 6.7 when apps run on Windows with Python 3.13+. Python 3.13+ changed `os.path.isabs`, so root-relative paths such as `/windows/win.ini` are no longer treated as absolute, which breaks Gradio's safe path-joining logic. Unauthenticated attackers can exploit this to read arbitrary files from the Gradio server, even when authentication is configured.

Mitigation

Version 6.7 fixes the issue.
