CVE-2017-16080
CVE-2017-16080 is a CWE-506 vulnerability in nodesass. O3 Security confirms whether CVE-2017-16080 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Nodesass is malware
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
nodesassnpmDescription
The nodesass package is a piece of malware that steals environment variables and sends them to attacker controlled locations.
All versions have been unpublished from the npm registry.
Recommendation
As this package is malware, if you find it installed in your environment, the real security concern is determining how it got there.
If you have found this installed in your environment, you should:
- Delete the package
- Clear your npm cache
- Ensure it is not present in any other package.json files on your system
- Regenerate your registry credentials, tokens, and any other sensitive credentials that may have been present in your environment variables.
Additionally, any service which may have been exposed via credentials in your environment variables, such as a database, should be reviewed for indicators of compromise as well.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nodesass. 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.
Remediation status
No patched version of nodesass has shipped for CVE-2017-16080 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2017-16080 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-2017-16080. 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-2017-16080 in your dependencies?
O3 detects CVE-2017-16080 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
