Gradio performs a non-constant-time comparison when comparing hashes
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
