Check this codebase for CVE-2021-34565 and fix it if it is affected.

What it is: CVE-2021-34565 is a critical vulnerability in Phoenix Contact WHA-GW-F2D2-0-AS- Z2-ETH, published on 31 Aug 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2021-34565 in the wild and no public exploit code.

Affected product: Phoenix Contact WHA-GW-F2D2-0-AS- Z2-ETH. 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.
