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 RapidLoad – Optimize Web Vitals Automatically plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on the uucss_data, update_rapidload_settings, wp_ajax_update_htaccess_file, uucss_update_rule, upload_rules, get_all_rules, update_titan_settings, preload_page, and activate_module functions in all versions up to, and including, 2.4.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify plugin settings or conduct SQL injection 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

The RapidLoad WordPress plugin lacks capability checks on multiple AJAX functions (uucss_data, update_rapidload_settings, wp_ajax_update_htaccess_file, uucss_update_rule, upload_rules, get_all_rules, update_titan_settings, preload_page, activate_module), allowing any authenticated user with Subscriber-level access to call these functions and modify plugin settings or execute SQL injection attacks.

MitigationUpdate to version 2.4.3 or later which adds proper capability checks. Additionally, implement nonce verification and parameterized queries to prevent SQL injection on all AJAX handlers.

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 RapidLoad plugin is installed
    Locate the plugin in wp-content/plugins/ directory or check via WordPress admin plugins list
    Affected if RapidLoad plugin is present on the WordPress site
  2. Determine installed RapidLoad version
    Check the plugin header in the main PHP file (typically rapidload.php) for the Version field, or query via wp-cli: wp plugin list --name=rapidload
    Affected if Version is lower than 2.4.3 or the version cannot be determined (indicating outdated installation)
  3. Confirm WordPress user roles exist
    Check if any user role with Subscriber-level or higher access exists on the site by querying wp_users table or via wp-cli: wp user list
    Affected if At least one user with Subscriber role or higher exists on the site
  4. Verify AJAX endpoints are accessible
    Check if the vulnerable AJAX actions are registered by examining plugin code for do_action('wp_ajax_*') calls or by testing access to /wp-admin/admin-ajax.php with action parameters like uucss_data, update_rapidload_settings, etc.
    Affected if Any of these AJAX actions (uucss_data, update_rapidload_settings, wp_ajax_update_htaccess_file, uucss_update_rule, upload_rules, get_all_rules, update_titan_settings, preload_page, activate_module) respond without capability validation

If RapidLoad plugin versions below 2.4.3 are installed AND any authenticated user with Subscriber-level access exists, the site is vulnerable to the described privilege escalation and potential SQL injection issues.
