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 Crafter CMS versionLocate the Crafter Studio or Crafter CMS installation and check the version file or admin interface for the installed version number (typically found in version.properties, about page, or startup logs).Affected if The installed version is 3.0.0 (or any version >= 3.0.0 but < 3.0.1).
-
Confirm Crafter Studio is runningAccess the Crafter Studio web interface (usually on port 8080 or configured HTTP port) or check if the service is listening and active.Affected if Crafter Studio web interface is accessible and accepts user input in any form field.
-
Check for unsanitized user input reflectionSubmit a harmless test script tag (such as <script>alert('XSS')</script>) in common input fields within Crafter Studio (e.g., site name, content fields, user profile fields) and observe if the script is reflected verbatim in the response page.Affected if The test script is reflected as-is in the web page without encoding or sanitization, indicating the XSS vulnerability is present.
If Crafter CMS version is >= 3.0.0 and < 3.0.1 and the Crafter Studio web interface reflects unsanitized user input, the environment is affected by this XSS vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data3.0.1
Upgrade Crafter Studio to a patched version or apply available security updates; implement input validation and output encoding as compensating controls until the patch can be applied.
