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
The Swift Performance Lite plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the ajax_handler() function in all versions up to, and including, 2.3.6.18. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve and modify settings.

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

The Swift Performance Lite WordPress plugin has a broken access control vulnerability in its ajax_handler() function. The function lacks proper capability checks, allowing any authenticated user with subscriber-level permissions (the lowest WordPress role) to access administrative AJAX endpoints and retrieve or modify plugin settings.

MitigationUpdate to version 2.3.6.19 or later which includes proper capability validation. Alternatively, add current_user_capability checks to the ajax_handler() function before processing any settings-related requests.

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. Verify Swift Performance Lite plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for a folder named 'swift-performance-lite' or 'swift-performance'. Alternatively, view the installed plugins list in WordPress admin under Plugins > Installed Plugins.
    Affected if The plugin folder exists in wp-content/plugins/
  2. Determine installed plugin version
    Open the main plugin file (usually swift-performance-lite.php or similar in the plugin folder) and locate the version in the plugin header comment, or check the version listed in WordPress admin plugins page.
    Affected if Version is lower than 2.3.6.19 (or version cannot be determined and the plugin is present)
  3. Confirm subscriber-level users exist
    In WordPress admin, go to Users > All Users and check if any users with the 'Subscriber' role exist. Alternatively, query the wp_usermeta table for users with wp_capabilities containing 'a:1:{s:10:"subscriber"'
    Affected if At least one subscriber-level user account exists in the WordPress installation
  4. Verify AJAX endpoint accessibility
    Test the ajax_handler endpoint by sending an authenticated request with a subscriber-level user credential to /wp-admin/admin-ajax.php?action=swift_performance_ajax (or similar plugin AJAX action). Use a tool like curl or Burp Suite to inspect the response.
    Affected if The request returns plugin settings data or executes without returning a capability/error response (response code 200 without permission denial)
  5. Inspect ajax_handler function for capability checks
    If code access is available, review the plugin source code in the ajax_handler() function. Search for 'current_user_can', 'capability', or 'manage_options' checks before processing settings-related AJAX actions.
    Affected if No capability checks are found before processing settings in the ajax_handler function

If the Swift Performance Lite plugin is installed with a version below 2.3.6.19 AND subscriber-level users exist in WordPress, the environment is vulnerable to CVE-2024-3722.
