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
A vulnerability has been discovered in appRain CMF version 4.0.5, consisting of a stored authenticated XSS due to a lack of proper validation of user input, through the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters in /apprain/developer/addons/update/row_manager.

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

A stored authenticated cross-site scripting (XSS) vulnerability exists in appRain CMF 4.0.5. The vulnerability stems from insufficient input validation on the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters within the /apprain/developer/addons/update/row_manager endpoint. An authenticated attacker can inject malicious JavaScript code that persists in the application and executes when other users access the affected functionality.

MitigationImplement strict input validation and output encoding for the affected parameters. Sanitize or reject special characters and HTML/script content in user inputs before storage, and properly encode data when rendering to prevent script execution.

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 appRain CMF version
    Locate the version file or check the admin dashboard for the installed version number. Look for version.php or similar version documentation files in the installation directory.
    Affected if The installed version is exactly 4.0.5
  2. Verify the vulnerable endpoint exists
    Check if the route /apprain/developer/addons/update/row_manager is accessible in the application by examining the routing configuration or attempting to access the URL.
    Affected if The endpoint exists and is routable in the application
  3. Confirm authentication access to the endpoint
    Verify that a user account exists with permissions to access the developer/addons section. Log in and check if the user can navigate to the addons management area.
    Affected if An authenticated user with addon management privileges exists in the system
  4. Inspect stored addon layout configuration
    Examine the database table or configuration file where addon settings are stored. Look for entries containing the 'layouts' and 'layouts_except' fields within the addon data.
    Affected if The database contains stored values in data[Addon][layouts] or data[Addon][layouts_except] that contain raw unescaped HTML or script tags
  5. Check for existing XSS payloads in addon settings
    Query the addon configuration storage for any JavaScript tags, script elements, or event handlers (onload, onerror, onclick) in the layout-related fields.
    Affected if The stored values contain unsanitized script tags or JavaScript event handlers that would execute when rendered

A user is affected if they are running appRain CMF version 4.0.5 and the application has stored values in the addon layout configuration parameters that contain unescaped HTML or JavaScript code.
