## What is CVE-2022-1118?

CVE-2022-1118 is a high-severity unsafe deserialization vulnerability in Rockwell Automation Connected Component Workbench, published on 17 May 2022. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

Connected Components Workbench (v13.00.00 and prior), ISaGRAF Workbench (v6.0 though v6.6.9), and Safety Instrumented System Workstation (v1.2 and prior (for Trusted Controllers)) do not limit the objects that can be deserialized. This allows attackers to craft a malicious serialized object that, if opened by a local user in Connected Components Workbench, may result in arbitrary code execution. This vulnerability requires user interaction to be successfully exploited

Weakness: CWE-502 (Deserialization of Untrusted Data)

Check this codebase for CVE-2022-1118 and fix it if it is affected.

What it is: CVE-2022-1118 is a high-severity unsafe deserialization vulnerability in Rockwell Automation Connected Component Workbench, published on 17 May 2022. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2022-1118 in the wild and no public exploit code.

Affected product: Rockwell Automation Connected Component Workbench. 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.
