Check this codebase for CVE-2024-38094 and fix it if it is affected.

What it is: CVE-2024-38094 is a high-severity unsafe deserialization vulnerability in Microsoft Sharepoint Server, published on 9 Jul 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: Yes. Attackers have exploited CVE-2024-38094 in the wild since at least 22 Oct 2024, including in ransomware campaigns.

Affected product: Microsoft Sharepoint Server. 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.
