CVE-2024-21519 is a medium-severity vulnerability in opencart/opencart, published on 22 Jun 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

This affects versions of the package opencart/opencart from 4.0.0.0. An Arbitrary File Creation issue was identified via the database restoration functionality. By injecting PHP code into the database, an attacker with admin privileges can create a backup file with an arbitrary filename (including the extension), within /system/storage/backup.

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.
