## What is GHSA-hh3j-9m59-p8vc?

GHSA-hh3j-9m59-p8vc is a denial of service vulnerability in bentoml, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Affected packages and fixed versions:
- bentoml (PyPI): affected all versions up to 1.3.9; no fix listed
- bentoml (PyPI): affected all versions up to 1.3.9; no fix listed

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
