No CVSS score has been assigned to CVE-2017-16034 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2017-16034?

CVE-2017-16034 affects the following packages: pidusage (npm). Ecosystems affected: npm.

How do I fix CVE-2017-16034?

Update pidusage to 1.1.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-16034 is resolved across your whole dependency graph.

How do I detect CVE-2017-16034 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pidusage, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2017-16034 if there is no patch (or I can't update yet)?

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.

Is CVE-2017-16034 actively exploited in the wild?

No public exploit code has been indexed for CVE-2017-16034 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.
