Check this codebase for CVE-2024-40767 and fix it if it is affected.
What it is: CVE-2024-40767 is a medium-severity path traversal vulnerability in n/a, published on 24 Jul 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-2024-40767 in the wild and no public exploit code.
Affected packages and fixed versions:
- nova (PyPI): affected all versions up to 27.4.0; no fix listed
- nova (PyPI): affected all versions up to 27.4.0; no fix listed
- nova (PyPI): affected from 28.0.0 up to 28.2.0; no fix listed
- nova (PyPI): affected from 29.0.0 up to 29.1.0; no fix listed
- Nova (PyPI): affected all versions up to 27.4.0; no fix listed
- Nova (PyPI): affected from 28.0.0 up to 28.2.0; no fix listed

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.

What is CVE-2024-40767?
CVE-2024-40767 is a medium-severity path traversal vulnerability in n/a, published on 24 Jul 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
In OpenStack Nova before 27.4.1, 28 before 28.2.1, and 29 before 29.1.1, by supplying a raw format image that is actually a crafted QCOW2 image with a backing file path or VMDK flat image with a descriptor file path, an authenticated user may convince systems to return a copy of the referenced file's contents from the server, resulting in unauthorized access to potentially sensitive data. All Nova deployments are affected. NOTE: this issue exists because of an incomplete fix for CVE-2022-47951 and CVE-2024-32498.
Weakness: CWE-552
