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 Marketing Cloud Engagement installationAccess the Marketing Cloud Engagement administration panel or contact Salesforce support to confirm the exact version and build number of your Marketing Cloud Engagement instanceAffected if Version cannot be determined or is older than the January 21, 2026 patch date
-
Locate the MicrositeUrl module configurationIn the Marketing Cloud Engagement admin interface, navigate to the MicrositeUrl or Web Microsites section under the Email Studio or Web Analytics module to verify if this functionality is enabledAffected if The MicrositeUrl module is enabled and accessible to users or API consumers
-
Review MicrositeUrl API endpoint exposureCheck the API exposure settings for MicrositeUrl endpoints in the Marketing Cloud Engagement API Manager or Web Services settings. Confirm whether these endpoints are publicly accessible or restricted to authorized users onlyAffected if MicrositeUrl API endpoints are exposed without proper authentication or IP restriction
-
Inspect web services request logs for anomalous patternsAccess the Marketing Cloud Engagement web services logs or API call logs. Look for requests to MicrositeUrl endpoints containing unusual argument patterns such as semicolons, pipe symbols, quote characters, or command separators in URL parametersAffected if Logs show malformed or suspicious argument patterns in microsite URL requests that suggest injection attempts
Your environment is affected if your Marketing Cloud Engagement version predates the January 21, 2026 patch AND the MicrositeUrl module is active and accessible.
