## What is CVE-2024-35219?

CVE-2024-35219 is a high-severity path traversal vulnerability in OpenAPITools openapi-generator, published on 27 May 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec. Prior to version 7.6.0, attackers can exploit a path traversal vulnerability to read and delete files and folders from an arbitrary, writable directory as anyone can set the output folder when submitting the request via the `outputFolder` option. The issue was fixed in version 7.6.0 by removing the usage of the `outputFolder` option. No known workarounds are available.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

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.
