npm install keycloak-connect@21.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls keycloak-connect

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-2237, inspect your project dependencies using npm:

npm ls keycloak-connect

Analyze the terminal output to locate any version of Keycloak connect in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 21.0.1), your application is affected.

Note: The npm ls keycloak-connect command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
