You're affected if you use CodeReady Workspaces versions 1.3.0 or earlier. To check if your version is vulnerable, run the following command: ls /etc/passwd (Note: This command checks for a specific file, but it may not detect all affected systems.)
This vulnerability is related to Red Hat's OpenShift Container Platform and is not directly related to CodeReady Workspaces itself, but rather an issue with the images used in it. If you don't recognize the name "CodeReady Workspaces", you're probably not affected.
