GHSA-q93m-25xv-94hh
GHSA-q93m-25xv-94hh is a Information Exposure vulnerability in typo3/cms-core. O3 Security confirms whether GHSA-q93m-25xv-94hh is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Problem
Backend users were able to insert arbitrary records and files into the TYPO3 clipboard without proper read permission checks, which allowed users to gather information about records and files they were not authorized to view.
Solution
Update to TYPO3 versions 10.4.57 ELTS, 11.5.51 ELTS, 12.4.46 ELTS, 13.4.31 LTS, 14.3.3 LTS that fix the problem described.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for typo3/cms-core. 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.
Fix
Update typo3/cms-core to 10.4.57 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q93m-25xv-94hh is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-q93m-25xv-94hh 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-q93m-25xv-94hh. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-q93m-25xv-94hh in your dependencies?
O3 detects GHSA-q93m-25xv-94hh across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
