### Official description

An XML External Entity (XXE) vulnerability exists in the Ambari/Oozie 
project, allowing an attacker to inject malicious XML entities. This

attacks. The issue has been fixed in both Ambari 2.7.9 and the trunk 
branch.

Check this codebase for CVE-2025-23195 and fix it if it is affected.

What it is: CVE-2025-23195 is a high-severity vulnerability in Apache Ambari, published on 21 Jan 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-23195 in the wild and no public exploit code.

Affected product: Apache Ambari. 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.
