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

Missing Authorization vulnerability in the CyberChimps Responsive Blocks plugin for WordPress (responsive-block-editor-addons) allows unauthenticated or unauthorized users to access functionality or data that should require proper capability checks. The plugin incorrectly configures access control security levels, potentially exposing sensitive operations or settings.

MitigationImplement proper WordPress capability checks (e.g., current_user_can()) on all AJAX actions, REST API endpoints, and admin functions. Update to the latest patched version of the plugin and audit all public-facing entry points for authorization bypasses.

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 the plugin is installed and active
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Responsive Blocks' or 'Responsive Block Editor Addons'. Check if it is activated.
    Affected if The plugin is installed and active in WordPress, exposing potential entry points for unauthorized access.
  2. Identify the installed plugin version
    Click on the plugin name in the Plugins list to view details, or inspect the plugin main file (usually in wp-content/plugins/responsive-block-editor-addons/) for the 'Version' header in the plugin comments.
    Affected if The installed version is older than the patched version released to address CVE-2026-32543.
  3. Inspect AJAX action handlers
    Examine the plugin's main PHP file and any included PHP files for do_action('wp_ajax_') and do_action('wp_ajax_nopriv_') calls. Check if these handlers include current_user_can() or similar capability checks before executing sensitive operations.
    Affected if AJAX actions are registered with 'nopriv' hooks (accessible to unauthenticated users) and lack capability verification checks.
  4. Review REST API endpoint registration
    Search plugin files for register_rest_route() calls. Inspect each endpoint's callback function to determine if it performs authorization checks (e.g., permission_callback that verifies user capabilities).
    Affected if REST API endpoints are registered without proper permission_callback functions that validate user capabilities.
  5. Test admin function access control
    As a non-administrator user (or unauthenticated user), attempt to access plugin functionality that should be restricted to administrators, such as plugin settings pages or form submission handlers.
    Affected if Sensitive admin functions or settings pages are accessible without proper WordPress capability checks (e.g., current_user_can('manage_options')).

A user is affected if the Responsive Blocks plugin is active and its AJAX handlers, REST API endpoints, or admin functions lack proper WordPress capability checks, allowing unauthorized access to sensitive operations.
