Check this codebase for CVE-2019-10094 and fix it if it is affected.

What it is: CVE-2019-10094 is a high-severity denial of service vulnerability in Apache Tika, published on 2 Aug 2019. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2019-10094 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.apache.tika:tika-core (Maven): affected from 1.7; fixed in 1.22
- org.apache.tika:tika-core (Maven): affected from 1.7; fixed in 1.22

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.
