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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for whatsapp-chat-exporter. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update whatsapp-chat-exporter to 0.9.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8c6x-g4fw-8rf4 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-8c6x-g4fw-8rf4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-8c6x-g4fw-8rf4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
