Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update DNN.PLATFORM to 10.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pf4h-vrv6-cmvr 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.

Frequently Asked Questions

DNN.PLATFORM allows specially crafted content in URLs could be used with TokenReplace and not be properly sanitized by some SkinObjects. This vulnerability is fixed in 10.0.1.
