## What is CVE-2023-45138?

CVE-2023-45138 is a critical cross-site scripting vulnerability in xwiki-contrib application-changerequest, published on 12 Oct 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Change Request is an pplication allowing users to request changes on a wiki without publishing the changes directly. Starting in version 0.11 and prior to version 1.9.2, it's possible for a user without any specific right to perform script injection and remote code execution just by inserting an appropriate title when creating a new Change Request. This vulnerability is particularly critical as Change Request aims at being created by user without any particular rights. The vulnerability has been fixed in Change Request 1.9.2. It's possible to workaround the issue without upgrading by editing the document `ChangeRequest.Code.ChangeRequestSheet` and by performing the same change as in the fix commit.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

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.
