Check this codebase for CVE-2017-5691 and fix it if it is affected.

What it is: CVE-2017-5691 is a critical vulnerability in 6th and 7th Generation Intel Core Processor Families, Intel Xeon E3-1500M v5 and v6 Processor Families, and Intel Xeon E3-1200 v5 and v6 Product Families., published on 26 Jul 2017. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2017-5691 in the wild and no public exploit code.

Affected product: 6th and 7th Generation Intel Core Processor Families, Intel Xeon E3-1500M v5 and v6 Processor Families, and Intel Xeon E3-1200 v5 and v6 Product Families.. 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.
