Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

[!IMPORTANT] This vulnerability only affects sites which are in the "dev" environment mode. If your production website is in "dev" mode, it has been misconfigured, and you should immediately swap it to "live" mode. See https://docs.silverstripe.org/en/developer_guides/debugging/environment_types/ for more information.

If a website has been set to the "dev" environment mode, a URL can be provided which includes an XSS payload which will be executed in the resulting error message.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/framework. 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 silverstripe/framework to 5.3.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mqf3-qpc3-g26q 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-mqf3-qpc3-g26q 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-mqf3-qpc3-g26q. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
