GHSA-h353-hc43-95vc is a high-severity (CVSS 8.8) Code Injection vulnerability in org.xwiki.commons:xwiki-commons-core. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-h353-hc43-95vc is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.commons:xwiki-commons-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 org.xwiki.commons:xwiki-commons-core to 12.6.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h353-hc43-95vc 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-h353-hc43-95vc 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-h353-hc43-95vc. 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-h353-hc43-95vc in your dependencies?
O3 detects GHSA-h353-hc43-95vc across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
