### Official description

Improper Input Validation vulnerability in Apache Hop Engine.This issue affects Apache Hop Engine: before 2.8.0.

Users are recommended to upgrade to version 2.8.0, which fixes the issue.

The variable not properly escaped is the "id", which is not directly accessible by users creating pipelines making the risk of exploiting this low.

This issue only affects users using the Hop Server component and does not directly affect the client.

Weakness: CWE-20 (Improper Input Validation)

What it is: CVE-2024-24683 is a medium-severity cross-site scripting vulnerability in Apache Hop Engine, published on 19 Mar 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-24683 in the wild and no public exploit code.

- org.apache.hop:hop (Maven): affected all versions; fixed in 2.8.0

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.
