Check this codebase for CVE-2021-25129 and fix it if it is affected.

What it is: CVE-2021-25129 is a high-severity path traversal vulnerability in HPE Cloudline CL5800 Gen9 Server; HPE Cloudline CL5200 Gen9 Server; HPE Cloudline CL4100 Gen10 Server; HPE Cloudline CL3100 Gen10 Server; HPE Cloudline CL5800 Gen10 Server, published on 29 Jan 2021. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2021-25129 in the wild and no public exploit code.

Affected product: HPE Cloudline CL5800 Gen9 Server; HPE Cloudline CL5200 Gen9 Server; HPE Cloudline CL4100 Gen10 Server; HPE Cloudline CL3100 Gen10 Server; HPE Cloudline CL5800 Gen10 Server. 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.
