## What is CVE-2024-21571?

CVE-2024-21571 is a high-severity code injection vulnerability in Snyk Code Agent, published on 6 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Snyk has identified a remote code execution (RCE) vulnerability in all versions of Code Agent. The vulnerability enables an attacker to execute arbitrary code within the Code Agent container. Exploiting this vulnerability would require an attacker to have network access to the Code Agent within the deployment environment. External exploitation of this vulnerability is unlikely and depends on both misconfigurations of the cluster and/or chaining with another vulnerability. However, internal exploitation (with a cluster misconfiguration) could still be possible.

Weakness: CWE-94 (Improper Control of Generation of Code)

Check this codebase for CVE-2024-21571 and fix it if it is affected.

What it is: CVE-2024-21571 is a high-severity code injection vulnerability in Snyk Code Agent, published on 6 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-21571 in the wild and no public exploit code.

Affected product: Snyk Code Agent. 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.
