Check this codebase for CVE-2022-28887 and fix it if it is affected.

What it is: CVE-2022-28887 is a medium-severity denial of service vulnerability in All F-Secure and WithSecure Endpoint Protection products for Windows & Mac F-Secure Linux Security (32-bit) F-Secure Linux Security (64-bit) F-Secure Atlant F-Secure Internet Gatekeeper, published on 12 Oct 2022. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2022-28887 in the wild and no public exploit code.

Affected product: All F-Secure and WithSecure Endpoint Protection products for Windows & Mac F-Secure Linux Security (32-bit) F-Secure Linux Security (64-bit) F-Secure Atlant F-Secure Internet Gatekeeper. 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.
