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.
-
Identify installed product versionCheck the version of IBM Cloud Pak for Automation or IBM Workflow Process Service installed in your environment. This can typically be found in the product's about section, installation logs, or by querying the deployment manifests.Affected if The installed version is exactly 21.0.2 for either product.
-
Confirm Web UI component is enabledVerify whether the Web UI interface is accessible and enabled in the deployment. This may involve checking the service configuration, load balancer settings, or testing connectivity to the Web UI endpoint.Affected if The Web UI is exposed and accessible to users.
-
Verify user authentication is configuredSince this XSS vulnerability requires an authenticated user, check if user authentication mechanisms (such as LDAP, SAML, or internal user registry) are configured for the Web UI.Affected if Users can authenticate to the Web UI.
-
Inspect Web UI for unexpected scriptsReview any custom scripts, user-supplied content, or third-party integrations that could be injecting JavaScript into Web UI pages. Check the HTML source of Web UI pages for any unencoded user input.Affected if User-controllable input appears in Web UI pages without proper output encoding.
You are affected if you are running exactly version 21.0.2 of IBM Cloud Pak for Automation or IBM Workflow Process Service with the Web UI enabled and user authentication configured.
