GHSA-7f88-5hhx-67m2
HIGHGHSA-7f88-5hhx-67m2 is a high-severity (CVSS 7.5) Uncontrolled Resource Consumption vulnerability in org.jboss.xnio:xnio-api. O3 Security confirms whether GHSA-7f88-5hhx-67m2 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
XNIO denial of service vulnerability
Blast Radius
org.jboss.xnio:xnio-apiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
A flaw was found in XNIO. The XNIO NotifierState that can cause a Stack Overflow Exception when the chain of notifier states becomes problematically large can lead to uncontrolled resource management and a possible denial of service (DoS). Version 3.8.14.Final is expected to contain a fix.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jboss.xnio:xnio-api. 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.jboss.xnio:xnio-api to 3.8.14.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7f88-5hhx-67m2 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-7f88-5hhx-67m2 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-7f88-5hhx-67m2. 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-7f88-5hhx-67m2 in your dependencies?
O3 detects GHSA-7f88-5hhx-67m2 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
