Attackers controlling any HF Space can return a parent-domain cookie that the shared client stores and automatically replays into all subsequent proxy requests to other legitimate Spaces, affecting all users of the same Gradio deployment.\n\n## Affected packages\n\n- `gradio < 6.15.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `gradio 6.15.0`","depth":"sunlit","depthScore":37,"depthScoreParts":{"impact":37.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
