### Official description

An issue was discovered in Tufin SecureTrack 18.1 with TufinOS 2.16 build 1179(Final). The Audit Report module is affected by a blind XXE vulnerability when a new Best Practices Report is saved using a special payload inside the xml input field.

Check this codebase for CVE-2018-18406 and fix it if it is affected.

What it is: CVE-2018-18406 is a critical vulnerability in n/a, published on 19 Jun 2019. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-18406 in the wild and no public exploit code.

Affected product: n/a. 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.
