Summary
Gradio performs a non-constant-time comparison when comparing hashes
Details

Impact

What kind of vulnerability is it? Who is impacted?

This vulnerability involves a timing attack in the way Gradio compares hashes for the analytics_dashboard function. Since the comparison is not done in constant time, an attacker could exploit this by measuring the response time of different requests to infer the correct hash byte-by-byte. This can lead to unauthorized access to the analytics dashboard, especially if the attacker can repeatedly query the system with different keys.

Patches

Yes, please upgrade to gradio>4.44 to mitigate this issue.

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

To mitigate the risk before applying the patch, developers can manually patch the analytics_dashboard dashboard to use a constant-time comparison function for comparing sensitive values, such as hashes. Alternatively, access to the analytics dashboard can be disabled.
