Check this codebase for CVE-2017-8033 and fix it if it is affected.

What it is: CVE-2017-8033 is a high-severity path traversal vulnerability in Cloud Controller API CAPI-release versions prior to v1.35.0 and cf-release versions prior to v268, published on 25 Jul 2017. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2017-8033 in the wild and no public exploit code.

Affected product: Cloud Controller API CAPI-release versions prior to v1.35.0 and cf-release versions prior to v268. 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.
