Check this codebase for CVE-2024-21421 and fix it if it is affected.

What it is: CVE-2024-21421 is a high-severity vulnerability in Microsoft Azure SDK, published on 12 Mar 2024. 
Exploitation: There is no known exploitation of CVE-2024-21421 in the wild and no public exploit code.

Affected product: Microsoft Azure SDK. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
