Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Cross-site scripting (XSS) vulnerability in OpenCms 6.0.3 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified search parameters.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Cross-site scripting (XSS) vulnerability in OpenCMS versions 6.0.3 and earlier allows remote attackers to inject arbitrary web script or HTML through unspecified search parameters. The vulnerability stems from insufficient input validation and sanitization in the search functionality.

MitigationImplement proper input validation and output encoding for all search parameters; consider upgrading to a supported OpenCMS version if still running legacy 6.x installations.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify OpenCMS version
    Locate the version file or check the admin interface for the installed Alkacon OpenCMS version number
    Affected if Installed version is 6.0.3, 6.0.2, or any earlier 6.x version
  2. Confirm search module is enabled
    Access the OpenCMS workplace and verify the search module functionality is available and accessible to users
    Affected if Search module is enabled and accessible to unauthenticated or low-privilege users
  3. Test search parameters for XSS
    Submit a benign XSS probe string (such as <script>alert(1)</script>) through the search input field and observe if it is reflected unescaped in the response
    Affected if Search parameters reflect input without HTML encoding or sanitization

Environment is affected if running OpenCMS 6.0.3 or earlier with the search module enabled and search inputs reflect unsanitized input directly in responses.

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.
