## What is CVE-2024-34084?

CVE-2024-34084 is a high-severity denial of service vulnerability in stacklok minder, published on 7 May 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Minder's `HandleGithubWebhook` is susceptible to a denial of service attack from an untrusted HTTP request.

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.
