Check this codebase for CVE-2025-28384 and fix it if it is affected.

What it is: CVE-2025-28384 is a critical path traversal vulnerability in n/a, published on 13 Jun 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-28384 exists.

Affected packages and fixed versions:
- openc3-cosmos-tool-iframe (RubyGems): affected all versions; no fix listed
- openc3-cosmos-tool-iframe (RubyGems): affected all versions; no fix listed
- openc3 (PyPI): affected all versions up to 6.0.0; no fix listed

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.
