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 vulnerability in baserCMS (baserCMS 4.1.0.1 and earlier versions, baserCMS 3.0.15 and earlier versions) allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

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 baserCMS versions 4.1.0.1 and earlier, and 3.0.15 and earlier, allows remote attackers to inject arbitrary JavaScript or HTML into web pages viewed by other users. The specific injection point is not specified in the advisory.

MitigationApply available vendor patches for baserCMS 4.x and 3.x to the latest respective versions. Until patches are applied, implement output encoding and input validation on all user-supplied data fields.

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. Confirm baserCMS is installed
    Identify baserCMS files in the web root directory. Look for the /lib/Baser folder or check for baserCMS-specific files and directories.
    Affected if baserCMS is present on the system
  2. Determine the installed baserCMS version
    Locate the version file within the baserCMS installation. Version information is typically stored in a version file within the baserCMS directory structure.
    Affected if The installed version cannot be determined or is not visible
  3. Compare version against affected ranges
    Match the installed version to the affected ranges: 3.0.0 to 3.0.15, or 4.0.0 to 4.1.0.1
    Affected if The installed version falls within 3.0.0-3.0.15 or 4.0.0-4.1.0.1
  4. Identify accessible user input features
    Check for active web-facing input forms such as comment submission, contact forms, or other content entry points that accept user-supplied data.
    Affected if User-accessible input forms are enabled and accessible on the site

The environment is affected if baserCMS is installed and the installed version falls within 3.0.0-3.0.15 or 4.0.0-4.1.0.1 with accessible user input fields.
