## What is CVE-2020-1192?

CVE-2020-1192 is a high-severity code injection vulnerability in Microsoft Visual Studio Code, published on 21 May 2020. 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

A remote code execution vulnerability exists in Visual Studio Code when the Python extension loads workspace settings from a notebook file. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would need to convince a target to open a specially crafted file in Visual Studio Code with the Python extension installed.
The update address the vulnerability by modifying the way Visual Studio Code Python extension enforces user settings.

Check this codebase for CVE-2020-1192 and fix it if it is affected.

What it is: CVE-2020-1192 is a high-severity code injection vulnerability in Microsoft Visual Studio Code, published on 21 May 2020. 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-2020-1192 in the wild and no public exploit code.

Affected product: Microsoft Visual Studio Code. 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.
