Description
In Eclipse Parsson before 1.0.4 and 1.1.3, a document with a large depth of nested objects can allow an attacker to cause a Java stack overflow exception and denial of service. Eclipse Parsson allows processing (e.g. parse, generate, transform and query) JSON documents.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.eclipse.parsson:parsson | ≥ 1.1.0&&< 1.1.3 | 1.1.3 |
| ☕Maven | org.eclipse.parsson:parsson | all versions | 1.0.4 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.eclipse.parsson:parsson. 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.eclipse.parsson:parsson to 1.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-7272 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 CVE-2023-7272 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 CVE-2023-7272. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
