CVE-2022-36127
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in Apache SkyWalking NodeJS Agent prior to 0.5.1. The vulnerability will cause NodeJS services that has this agent installed to be unavailable if the OAP is unhealthy and NodeJS agent can't establish the connection.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Apache SkyWalking NodeJS Agent prior to 0.5.1 contains a denial-of-service vulnerability where the agent fails to handle OAP backend connection failures gracefully. When the OAP (Observability Analysis Platform) becomes unhealthy or unreachable, the agent's connection handling causes the entire NodeJS service to become unavailable rather than degrading gracefully.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate SkyWalking NodeJS Agent installationSearch your NodeJS project for @skywalking/apm-nodejs-agent in package.json, package-lock.json, or node_modules directoryAffected if The SkyWalking NodeJS Agent package is present in the project dependencies
-
Determine installed agent versionRun 'npm list @skywalking/apm-nodejs-agent' or inspect the version field in node_modules/@skywalking/apm-nodejs-agent/package.jsonAffected if The installed version is lower than 0.5.1
-
Verify OAP backend connection is configuredSearch your application startup code, environment variables, or agent configuration for SW_OAP_ADDRESS, collector server address, or similar OAP endpoint settingsAffected if An OAP backend address is configured and the agent attempts connection to it
Your environment is affected if the SkyWalking NodeJS Agent version is below 0.5.1 and an OAP backend address is configured, making your service vulnerable to denial of service when the OAP becomes unreachable.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped0.5.1
Upgrade the Apache SkyWalking NodeJS Agent to version 0.5.1 or later, which implements proper connection failure handling that prevents service disruption when the OAP backend is unavailable.
0.5.1 or latest stable release
- 1. Identify the current SkyWalking NodeJS Agent version in use by checking package.json or node_modules
- 2. Update the agent dependency to version 0.5.1 or later using your package manager (e.g., npm install @skywalking/[email protected] or latest)
- 3. Restart the NodeJS service to load the updated agent
- 4. Test that the service remains available when the OAP backend is unavailable or unhealthy
