## What is GHSA-8c6x-g4fw-8rf4?

GHSA-8c6x-g4fw-8rf4 is a cross-site scripting vulnerability in Whatsapp-Chat-Exporter, published on 10 Jul 2023. 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

### Impact
A Cross-Site Scripting (XSS) vulnerability was found in the HTML output of chats. XSS is intended to be mitigated by Jinja's escape function. However, `autoescape=True` was missing when setting the environment. Although the actual impact is low, considering the HTML file is being viewed offline, an adversary may still be able to inject malicious payloads into the chat through WhatsApp. All users are affected.

### Patches
The vulnerability is patched in 0.9.5. All users are strongly advised to update the exporter to the latest version.

### Workarounds
No workaround is available. Please update the exporter to the latest version.

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.
