How to Fix CVE-2021-42228

To remediate this vulnerability, upgrade all affected Kindeditor dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

kindeditor fixed: Latest secure release 
npm install kindeditor@Latest secure release
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 kindeditor

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-42228, inspect your project dependencies using npm:

npm ls kindeditor

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

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