CVE-2022-30284
CRITICALCVE-2022-30284 is a critical-severity (CVSS 9) CWE-88 vulnerability in python-libnmap. 2 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2022-30284 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Argument injection in python-libnmap
Blast Radius
python-libnmapReal-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
In the python-libnmap package through 0.7.2 for Python, remote command execution can occur (if used in a client application that does not validate arguments). NOTE: the vendor believes it would be unrealistic for an application to call NmapProcess with arguments taken from input data that arrived over an untrusted network, and thus the CVSS score corresponds to an unrealistic use case. None of the NmapProcess documentation implies that this is an expected use case
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for python-libnmap. 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 python-libnmap to 0.7.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-30284 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-2022-30284 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-2022-30284. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-30284 in your dependencies?
O3 detects CVE-2022-30284 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
