Check this codebase for CVE-2023-30513 and fix it if it is affected.

What it is: CVE-2023-30513 is a high-severity vulnerability in Jenkins Kubernetes Plugin, published on 12 Apr 2023. 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-2023-30513 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.csanchez.jenkins.plugins:kubernetes (Maven): affected all versions; fixed in 3910.ve59cec5e33ea
- org.csanchez.jenkins.plugins:kubernetes (Maven): affected all versions; fixed in 3910.ve59cec5e33ea

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.
