Exploitation: There is no known exploitation of CVE-2018-7793 in the wild and no public exploit code.

Affected product: Schneider Electric SE FoxView HMI SCADA (All Foxboro DCS, Foxboro Evo, and IA Series versions prior to Foxboro DCS Control Core Services 9.4 (CCS 9.4) and FoxView 10.5.). 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.
