### Official description

A vulnerability in the ConfD CLI and the Cisco  Crosswork Network Services Orchestrator CLI could allow an authenticated, low-privileged, local attacker to read and write arbitrary files as root on the underlying operating system.

Check this codebase for CVE-2024-20326 and fix it if it is affected.

What it is: CVE-2024-20326 is a high-severity command injection vulnerability in Cisco ConfD, published on 16 May 2024. 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-2024-20326 in the wild and no public exploit code.

Affected product: Cisco ConfD. 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.
