GHSA-9xxv-q6pp-96wq
LOWGHSA-9xxv-q6pp-96wq is a low-severity (CVSS 2.4) Cross-site Scripting (XSS) vulnerability in concrete5/concrete5. O3 Security confirms whether GHSA-9xxv-q6pp-96wq is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Concrete CMS Stored XSS
Blast Radius
concrete5/concrete5Real-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
Concrete CMS before 9.2.3 allows Stored XSS on the Admin Dashboard via /dashboard/system/basics/name. (8.5 and earlier are unaffected.)
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | concrete5/concrete5 | ≥ 9.0.0&&< 9.2.3 | 9.2.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for concrete5/concrete5. 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 concrete5/concrete5 to 9.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9xxv-q6pp-96wq 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-9xxv-q6pp-96wq 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-9xxv-q6pp-96wq. 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-9xxv-q6pp-96wq in your dependencies?
O3 detects GHSA-9xxv-q6pp-96wq across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
