## What is CVE-2024-29006?

CVE-2024-29006 is a critical authentication bypass vulnerability in Apache Cloudstack, published on 4 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

By default the CloudStack management server honours the x-forwarded-for HTTP header and logs it as the source IP of an API request. This could lead to authentication bypass and other operational problems should an attacker decide to spoof their IP address this way. Users are recommended to upgrade to CloudStack version 4.18.1.1 or 4.19.0.1, which fixes this issue.

Check this codebase for CVE-2024-29006 and fix it if it is affected.

What it is: CVE-2024-29006 is a critical authentication bypass vulnerability in Apache Cloudstack, published on 4 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-29006 in the wild and no public exploit code.

Affected product: Apache Cloudstack. 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.
