## What is CVE-2020-6650?

CVE-2020-6650 is a high-severity code injection vulnerability in Eaton UPS Companion Software, published on 23 Mar 2020. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

UPS companion software v1.05 & Prior is affected by ‘Eval Injection’ vulnerability.

Check this codebase for CVE-2020-6650 and fix it if it is affected.

What it is: CVE-2020-6650 is a high-severity code injection vulnerability in Eaton UPS Companion Software, published on 23 Mar 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-2020-6650 in the wild and no public exploit code.

Affected product: Eaton UPS Companion Software. 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.
