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 checksWork through these to decide whether this CVE applies to you.
-
Confirm WP Accessibility Helper plugin is installedCheck the WordPress plugins directory (wp-content/plugins/) for a folder named 'wp-accessibility-helper', 'wp-accessibility-helper-pro', or similar WAH plugin folders. Alternatively, list installed plugins via WP-CLI: wp plugin list --search='*accessibility*'Affected if The plugin folder exists in the plugins directory and the plugin is active
-
Retrieve the installed plugin versionOpen the main plugin PHP file (usually wp-accessibility-helper.php or wah.php in the plugin folder) and locate the 'Version:' field in the plugin header comment at the top. Or run: grep -i 'Version:' /path/to/wp-content/plugins/*/wp-accessibility-helper.phpAffected if The version number found is lower than 0.6.2.6 (e.g., 0.6.2.5, 0.6.2.0, etc.)
-
Check for unauthenticated AJAX endpointsExamine the plugin's main PHP file for wp_ajax_ and wp_ajax_nopriv_ action hooks. Look for registrations like add_action('wp_ajax_wah_...') or add_action('wp_ajax_nopriv_wah_...') that handle user settings, data retrieval, or configuration changes without capability checksAffected if AJAX endpoints are registered with wp_ajax_nopriv_ hooks and lack current_user_can() or similar authorization checks before processing requests
-
Verify public-facing functionality lacks capability checksSearch the plugin source code for function definitions that modify settings, retrieve user data, or access sensitive information. Look for the absence of checks like 'if ( ! current_user_can(...) )' or 'if ( ! is_user_logged_in() )' before sensitive operationsAffected if Functions handling user data, settings, or content modifications can be executed by any visitor without authentication or authorization
A user is affected if the WP Accessibility Helper plugin is installed with a version lower than 0.6.2.6 and the plugin exposes functionality accessible to unauthenticated users without proper authorization checks.
