Check this codebase for CVE-2019-10930 and fix it if it is affected.

What it is: CVE-2019-10930 is a high-severity vulnerability in Siemens AG All other SIPROTEC 5 device types with CPU variants CP300 and CP100 and the respective Ethernet communication modules, published on 11 Jul 2019. 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-2019-10930 in the wild and no public exploit code.

Affected product: Siemens AG All other SIPROTEC 5 device types with CPU variants CP300 and CP100 and the respective Ethernet communication modules. 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.
