Check this codebase for CVE-2020-8130 and fix it if it is affected.

What it is: CVE-2020-8130 is a medium-severity command injection vulnerability in Canonical Ubuntu Linux, published on 24 Feb 2020. 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-2020-8130 in the wild and no public exploit code.

Affected packages and fixed versions:
- rake (RubyGems): affected all versions; fixed in 12.3.3
- rake (RubyGems): affected all versions; fixed in 12.3.3

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.
