OSSEVA FOR NODE.JS
Node.js support — patched, protected, operated.
OSSeva provides Node.js support for versions 14, 16, 18, 20 and 22, including patched builds for 14, 16, 18 and 20 after the community stops fixing them, and for 22 after its community end of life on 30 April 2027. Drop-in CVE patches cover EOL community versions no longer receiving upstream security fixes. HTTP/2 CONTINUATION flood, prototype pollution, and V8 engine vulnerabilities covered for the versions running in your production environment.

Why now
Node.js 14 and 16 are fully end-of-life
Node.js 14.x reached EOL in April 2023. Node.js 16.x reached EOL in September 2023. Many long-lived services still run them, with no upstream CVE patch path since EOL.
HTTP/2 request-flood classes keep landing on the server runtime
HTTP/2 frame handling has produced repeated denial-of-service advisories across every major server implementation, Node.js included — the CONTINUATION flood class being the best known. These are reachable by any unauthenticated client that can open a connection, which makes them a standing risk for any Node.js version no longer receiving upstream fixes.
Node.js upgrade paths involve npm ecosystem compatibility risk
Moving from Node.js 14 to 18 or 20 requires validating every npm dependency against the new V8 engine and libuv version. For large microservice portfolios, that's a months-long compatibility validation exercise — not a weekend task.

How it installs
OSSeva artifacts arrive via your existing package infrastructure. Pull the patched version the same way you pull upstream today — just from the OSSeva registry.
FROM artifacts.osseva.io/node:18.20.3-osseva-1-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
EXPOSE 3000
CMD ["node", "server.js"]# Add OSSeva apt repository
curl -fsSL https://packages.osseva.io/gpg | sudo gpg --dearmor -o /usr/share/keyrings/osseva.gpg

sudo apt-get update
sudo apt-get install -y osseva-nodejs-18Migrate from Community Node.js (EOL)
Node.js 14.x and 16.x are fully EOL with no upstream patches. Enterprises running large microservice portfolios on these versions face a multi-month compatibility validation exercise before they can upgrade. OSSeva provides CVE coverage for your current version on your upgrade timeline.
Pricing model
OSSeva for Node.js is priced per application runtime — not per core or per deployment instance. Book a discovery call for a quote.
Does OSSeva patch V8 (the JavaScript engine) separately from Node.js?
V8 CVEs are covered as part of the Node.js engagement. When a V8 vulnerability is disclosed, OSSeva assesses impact on each covered Node.js version and backports the fix as part of the Node.js patched build. You do not need a separate V8 engagement.
Does OSSeva cover npm or yarn supply chain vulnerabilities?
OSSeva Assure includes transitive npm dependency vulnerability scanning for your applications. This is separate from Node.js runtime CVEs — it covers your application's npm dependency tree for known vulnerabilities. We provide a prioritized remediation report.
What is the HTTP/2 CONTINUATION flood attack?
The CONTINUATION flood attack exploits the HTTP/2 protocol's CONTINUATION frame mechanism. An attacker sends a stream of CONTINUATION frames without closing the stream, causing the server to buffer unlimited headers in memory until OOM or crash. OSSeva's patched Node.js build limits CONTINUATION frame count per stream.
We use Node.js with PM2 for clustering. Is that configuration supported?
Yes. OSSeva supports Node.js in standalone, cluster mode, and PM2-managed deployments. OSSeva Operate includes PM2 cluster operational support — configuration review, worker process monitoring, and restart policy management.
Does OSSeva support Node.js in containerized / Kubernetes environments?
Yes. OSSeva provides patched Node.js Docker images (Alpine and Debian variants) suitable for Kubernetes deployments. The images are compatible with existing Kubernetes manifests — you update the image tag, nothing else changes.
Who provides Node.js support besides the OpenJS Foundation?
The OpenJS Foundation and the Node.js project publish the release lines and stop fixing each one at end of life. Other options are commercial vendors that bundle Node.js, cloud platforms that run it for you, and third-party support companies. OSSeva is a third-party option: one contract across your runtime, database and messaging stack, end-of-life Node.js versions included, and patched builds that run wherever you run Node.js.
Does OSSeva support current Node.js versions or only end-of-life ones?
Both. OSSeva's support matrix lists Node.js 14.x, 16.x, 18.x and 20.x as end of life with OSSeva patches active, and 22.x as current (Maintenance LTS, with community end of life on 30 April 2027), also with patches active. Assure adds Node.js version upgrade path planning, and Operate includes Node.js major version migration execution when you are ready to move.
How is OSSeva Node.js support priced?
OSSeva Node.js support is priced per application runtime. Patch covers quarterly CVE patches, Assure adds 24/7 reactive support, npm dependency scanning and compliance documentation, and Operate adds proactive 24/7 monitoring and managed operations with a 15-minute P1 SLA. OSSeva Operate patches Critical CVEs (CVSS ≥ 9.0) within 48 hours and High within 7 days. Book a discovery call for a quote.
