CVE-2014-8883
MEDIUMCVE-2014-8883 is a medium-severity (CVSS 5.3) vulnerability in nhouston. O3 Security confirms whether CVE-2014-8883 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Directory Traversal in nhouston
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
nhoustonnpmDescription
All versions of the static file server module nhouston are vulnerable to directory traversal. An attacker can provide input such as ../ to read files outside of the served directory.
Recommendation
It is recommended that a different module be used, as we have been unable to reacher the maintainer of this module. We will continue to reach out to them, and if an update becomes available that fixes the issue, we will update this advisory accordingly.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nhouston. 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 nhouston has shipped for CVE-2014-8883 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-2014-8883 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-2014-8883. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
