## What is GHSA-f36p-42jv-8rh2?

GHSA-f36p-42jv-8rh2 is a cross-site scripting vulnerability in com.wire.bots:lithium, published on 30 Sep 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

### Impact
A  XSS vulnerability in the provided (outdated) Swagger-UI is exploitable in applications using lithium with Swagger-UI enabled.
This allows an attacker gain Remote Code Execution (RCE) and potentially exfiltrate secrets in the context of this swagger session.

### Patches
The used swagger-ui was updated by switching to the latest version of dropwizard-swagger in 8b9b406d608fe482ec0e7adf8705834bca92d7df

### Workarounds
The risk of injected external content can be reduced by setting up a [Content-Security-Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy).

What it is: GHSA-f36p-42jv-8rh2 is a cross-site scripting vulnerability in com.wire.bots:lithium, published on 30 Sep 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of GHSA-f36p-42jv-8rh2 in the wild and no public exploit code.

Affected packages and fixed versions:
- com.wire.bots:lithium (Maven): affected all versions; no fix listed
- com.wire.bots:lithium (Maven): affected all versions; no fix listed
- com.wire:lithium (Maven): affected all versions; fixed in 3.4.2
- com.wire:lithium (Maven): affected all versions; fixed in 3.4.2

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.
