Description

Gradio before version 6.15.0 contains a cookie injection vulnerability that allows remote attackers to perform cross-Space session fixation by exploiting a shared module-level HTTP client used across all users in the reverse proxy endpoint. 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.
