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

Missing authorization checks in the Backend Routing of TYPO3 CMS versions 9.0.0‑9.5.54, 10.0.0‑10.4.53, 11.0.0‑11.5.47, 12.0.0‑12.4.36, and 13.0.0‑13.4.17 allow backend users to directly invoke AJAX backend routes without having access to the corresponding backend modules.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for typo3/cms-workspaces. 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 typo3/cms-workspaces to 12.4.37 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2fhw-2j7m-mr4m 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-2fhw-2j7m-mr4m 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-2fhw-2j7m-mr4m. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
