## What is CVE-2026-111218?

CVE-2026-111218 is a high-severity command injection vulnerability in Netgate pfSense CE, published on 15 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.

Check this codebase for CVE-2026-111218 and fix it if it is affected.

What it is: CVE-2026-111218 is a high-severity command injection vulnerability in Netgate pfSense CE, published on 15 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-111218 exists.

Affected product: Netgate pfSense CE. 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.
