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

The alttext-ai plugin for WordPress contains a missing authorization vulnerability where the application fails to properly validate user permissions before allowing access to the Download Alt Text AI functionality. This allows attackers to exploit incorrectly configured access control security levels, potentially accessing or downloading alt text data they should not have permission to access.

MitigationImplement proper authorization checks on all sensitive endpoints and functions within the plugin, ensuring that user permissions are validated before executing any data access or download operations.

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 alttext-ai plugin is installed
    Navigate to WordPress admin dashboard, go to Plugins > Installed Plugins, and search for 'alttext-ai' or check the wp-content/plugins/ directory for an 'alttext-ai' folder
    Affected if The plugin is present and active in the WordPress installation
  2. Identify the Download Alt Text AI functionality
    Examine the plugin files for any admin pages, AJAX handlers, or REST API endpoints related to 'Download Alt Text' or 'alt text' functionality - look in the plugin's main PHP file and any admin/submenu configuration
    Affected if The plugin exposes a download feature for alt text data
  3. Verify authorization controls on the download endpoint
    Review the plugin code to check if the download function includes capability checks (such as 'manage_options' or 'edit_posts') or nonce validation before allowing access to the alt text download functionality
    Affected if No capability check or insufficient permission validation exists before executing the download operation
  4. Test access with limited user account
    Create or use a WordPress user account with Subscriber or Contributor role (lowest privilege), then attempt to access the Download Alt Text AI feature via its URL or AJAX action
    Affected if A low-privilege user can successfully access or trigger the download functionality without proper authorization rejection

If the alttext-ai plugin is active and the download functionality can be accessed by users without appropriate WordPress capability checks, the environment is affected by this authorization bypass vulnerability.
