## What is GHSA-j3rq-4xjw-xg63?

GHSA-j3rq-4xjw-xg63 is a vulnerability in github.com/edgelesssys/marblerun, published on 4 Dec 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

### Impact
Any CLI command issued to a Coordinator after the Manifest has been set, is susceptible to be redirected to another MarbleRun Coordinator instance, which runs the same binary, but potentially a different manifest.

### Patches
 The issue has been patched in [`v1.4.0`](https://github.com/edgelesssys/marblerun/releases/tag/v1.4.0)

### Workarounds

Directly using the REST API of the Coordinator and manually verifying and pinning the certificate to a set Manifest avoids the issue.

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.
