GHSA-4q2w-rw7m-xqw6
CRITICALGHSA-4q2w-rw7m-xqw6 is a critical-severity (CVSS 9.8) vulnerability in nnabla. O3 Security confirms whether GHSA-4q2w-rw7m-xqw6 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Sony Neural Network Libraries reliance on untrusted inputs prior to v1.0.10

nnablaReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
nbla/logger.cpp in libnnabla.a in Sony Neural Network Libraries (aka nnabla) prior to v1.0.10 relies on the HOME environment variable, which might be untrusted.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | nnabla | all versions | 1.0.10 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nnabla. 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 nnabla to 1.0.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4q2w-rw7m-xqw6 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-4q2w-rw7m-xqw6 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-4q2w-rw7m-xqw6. 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-4q2w-rw7m-xqw6 in your dependencies?
O3 detects GHSA-4q2w-rw7m-xqw6 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
