CVE-2021-43830 is a high-severity SQL injection vulnerability in opf openproject, published on 14 Dec 2021. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

OpenProject is a web-based project management software. OpenProject versions >= 12.0.0 are vulnerable to a SQL injection in the budgets module. For authenticated users with the "Edit budgets" permission, the request to reassign work packages to another budget unsufficiently sanitizes user input in the `reassign_to_id` parameter. The vulnerability has been fixed in version 12.0.4. Versions prior to 12.0.0 are not affected. If you're upgrading from an older version, ensure you are upgrading to at least version 12.0.4. If you are unable to upgrade in a timely fashion, the following patch can be applied: https://github.com/opf/openproject/pull/9983.patch

Check this codebase for CVE-2021-43830 and fix it if it is affected.

What it is: CVE-2021-43830 is a high-severity SQL injection vulnerability in opf openproject, published on 14 Dec 2021. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2021-43830 in the wild and no public exploit code.

Affected product: opf openproject. 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.
