## What is CVE-2023-35116?

CVE-2023-35116 is a medium-severity denial of service vulnerability in Fasterxml Jackson-Databind, published on 14 Jun 2023. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

jackson-databind through 2.15.2 allows attackers to cause a denial of service or other unspecified impact via a crafted object that uses cyclic dependencies. NOTE: the vendor's perspective is that this is not a valid vulnerability report, because the steps of constructing a cyclic data structure and trying to serialize it cannot be achieved by an external attacker.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling)

Check this codebase for CVE-2023-35116 and fix it if it is affected.

What it is: CVE-2023-35116 is a medium-severity denial of service vulnerability in Fasterxml Jackson-Databind, published on 14 Jun 2023. 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-2023-35116 in the wild and no public exploit code.

Affected product: Fasterxml Jackson-Databind. 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.
