How to Fix GHSA-hh3j-9m59-p8vc

To remediate this vulnerability, upgrade all affected Bentoml dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

bentoml fixed: Latest secure release 
pip install bentoml>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show bentoml

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-hh3j-9m59-p8vc, inspect your installed packages using pip:

pip show bentoml

Analyze the terminal output to locate any version of Bentoml in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show bentoml command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Bentoml, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In bentoml/bentoml version 1.3.9, the `/login` endpoint of the newly integrated Gradio app is vulnerable to a Denial of Service (DoS) attack. This vulnerability can be exploited by appending characters, such as dashes (-), to the end of a multipart boundary in an HTTP request. The server continuously processes each character, leading to excessive resource consumption and rendering the service unavailable. The issue is unauthenticated and does not require any user interaction.
