Check this codebase for CVE-2025-52486 and fix it if it is affected.

What it is: CVE-2025-52486 is a medium-severity cross-site scripting vulnerability in Dnnsoftware Dotnetnuke, published on 21 Jun 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2025-52486 in the wild and no public exploit code.

- DNN.PLATFORM (NuGet): affected from 6.0.0; fixed in 10.0.1

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.
