EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
A stack overflow in the XML.toJSONObject component of hutool-json v5.8.10 and org.json:json before version 20230227 allows attackers to cause a Denial of Service (DoS) via crafted JSON or XML data.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | cn.hutool:hutool-json | all versions | 5.8.25 |
| ☕Maven | org.json:json | all versions | 20230227 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cn.hutool:hutool-json. 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 cn.hutool:hutool-json to 5.8.25 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3vqj-43w4-2q58 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-3vqj-43w4-2q58 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-3vqj-43w4-2q58. 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-3vqj-43w4-2q58 in your dependencies?
O3 detects GHSA-3vqj-43w4-2q58 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
