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

A Missing Authorization vulnerability exists in the Passionate Brains 'Add Expires Headers & Optimized Minify' WordPress plugin (versions through 3.2.0), allowing attackers to exploit incorrectly configured access control security levels. This likely enables unauthorized users to access administrative functions related to expires header configuration and minification settings without proper capability verification.

MitigationUpdate to the latest plugin version once available, and review administrative endpoints to ensure all actions requiring authorization properly validate user capabilities.

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
    Navigate to WordPress admin dashboard > Plugins and locate 'Add Expires Headers & Optimized Minify' by Passionate Brains, or check the plugin files in wp-content/plugins/ for the plugin folder
    Affected if the plugin is present in the WordPress installation
  2. Check the installed version
    View the plugin version in the WordPress Plugins admin page, or open the main plugin PHP file and look for the Version header in the plugin comment block
    Affected if the version is 3.2.0 or any earlier version through 3.2.0
  3. Identify admin endpoints handling expires headers and minification
    Examine plugin PHP files for admin action hooks (such as admin_post_, wp_ajax_, or admin_menu entries) that handle expires header configuration or minification settings. Common locations include the main plugin file or dedicated admin class files
    Affected if admin action handlers exist for expires headers or minification features and the plugin version is within affected range
  4. Verify capability checks on vulnerable admin actions
    Review the code in identified admin action handlers to confirm they include current_user_can() or similar capability verification before processing requests. Check both AJAX handlers (wp_ajax_) and form POST handlers (admin_post_)
    Affected if the admin action handlers for expires headers or minification lack proper current_user_can() capability checks before executing configuration changes
  5. Test unauthorized access to admin functions
    If you have access to the site, attempt to access the identified admin endpoints while logged in as a subscriber-level (or non-administrator) user account, or use a tool like Burp Suite to send requests to admin action URLs without proper authentication headers
    Affected if a low-privilege user can successfully modify expires header or minification settings without receiving a permission denied response

Your environment is affected if the 'Add Expires Headers & Optimized Minify' plugin version is 3.2.0 or earlier AND admin endpoints handling expires headers or minification lack proper capability verification checks.
