Low Risk
This Affects:
gradioTL;DR
Affected versions of this package are vulnerable to Denial of Service (DoS) due to improper enforcement of file size limits during uploads. An attacker can bypass the user-defined max_file_size by uploading a file with an excessively long filename, potentially exhausting server resources. This patch resolves the issue by correctly passing the max_file_size to the MultiPartParser through the GradioMultiPartParser class.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
gradio is vulnerable to Denial of Service (DoS) in versions 4.0.0 - 5.34.2.
