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.
