Description

phpMyFAQ prior to 3.2.0-beta.2 contains a cross-site scripting vulnerability. When an administrator restores a backup from a file, it's possible to trigger an error with a specially crafted file that can be displayed on the web page. Since the error message contains the invalid part of the file, any JavaScript code in the file is executed.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for thorsten/phpmyfaq, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update thorsten/phpmyfaq to 3.2.0-beta.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-3469 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
