Check this codebase for CVE-2018-0679 and fix it if it is affected.

What it is: CVE-2018-0679 is a medium-severity cross-site scripting vulnerability in multiple FXC Inc. network devices (Managed Ethernet switch FXC5210/5218/5224 firmware prior to version Ver1.00.22, Managed Ethernet switch FXC5426F firmware prior to version Ver1.00.06, Managed Ethernet switch FXC5428 firmware prior to version Ver1.00.07, Power over Ethernet (PoE) switch FXC5210PE/5218PE/5224PE firmware prior to version Ver1.00.14, and Wireless LAN router AE1021/AE1021PE firmware all versions), published on 15 Nov 2018. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2018-0679 in the wild and no public exploit code.

Affected product: multiple FXC Inc. network devices (Managed Ethernet switch FXC5210/5218/5224 firmware prior to version Ver1.00.22, Managed Ethernet switch FXC5426F firmware prior to version Ver1.00.06, Managed Ethernet switch FXC5428 firmware prior to version Ver1.00.07, Power over Ethernet (PoE) switch FXC5210PE/5218PE/5224PE firmware prior to version Ver1.00.14, and Wireless LAN router AE1021/AE1021PE firmware all versions). 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.
