gradio is vulnerable to Session Fixation
60
Medium Risk
This Affects:
gradioTL;DR
In affected versions, the /proxy= reverse proxy reused a shared httpx.AsyncClient across requests, causing cookies set by one proxied *.hf.space instance to be stored and replayed to other *.hf.space targets. A malicious Space could abuse this behavior by setting attacker-controlled cookies scoped to the parent hf.space domain, leading to cross-Space session fixation and unintended session sharing between proxied applications.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
