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 BlueSpiceUserSidebar extension of BlueSpice allows user with regular account and edit permissions to inject arbitrary HTML into the personal menu navigation of their own and other users. This allows for targeted attacks.

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 · high confidence

Cross-site scripting (XSS) vulnerability in BlueSpiceUserSidebar extension allows authenticated users with edit permissions to inject arbitrary HTML/script into the personal menu navigation, which then executes when other users view the affected navigation.

MitigationImplement proper input sanitization and output escaping on all user-controllable data entering the personal menu navigation; validate and sanitize HTML before storage and escape all untrusted data on output.

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 BlueSpice installation version
    Access the admin dashboard or check the version file (typically includes a version.php or About page in the administration panel). Compare the installed version number against the affected range: 4.1.0 through 4.2.0.
    Affected if The installed version is 4.1.0 or higher but lower than 4.2.1.
  2. Confirm BlueSpiceUserSidebar extension is enabled
    Navigate to the extension management area in the BlueSpice admin panel or check the LocalSettings.php file for the line: wfLoadExtension( 'BlueSpiceUserSidebar' ).
    Affected if The extension is loaded and active.
  3. Verify edit permission exists for user accounts
    Check user group permissions in the BlueSpice permission manager. Look for groups or users assigned the 'edit' right, particularly the 'sidebar-edit' permission if exposed.
    Affected if Authenticated users have edit permissions, allowing them to modify personal menu navigation.
  4. Inspect personal menu navigation for unexpected entries
    Access the personal menu configuration (typically via User preferences or Sidebar settings). Examine all navigation items for suspicious HTML tags, script elements, or encoded payloads.
    Affected if Any navigation item contains unescaped HTML, script tags, or javascript: URIs.

Your environment is affected if you run Hallowelt Bluespice version 4.1.0 through 4.2.0 with the BlueSpiceUserSidebar extension enabled and users possess edit permissions that allow modifying personal menu navigation items.

Upgrade available Upgrade to 4.2.1 or later

Interim mitigation

Implement proper input sanitization and output escaping on all user-controllable data entering the personal menu navigation; validate and sanitize HTML before storage and escape all untrusted data on output.
