NVD · unedited
Missing Authorization vulnerability in Ads by WPQuads Ads by WPQuads quick-adsense-reloaded allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Ads by WPQuads: from n/a through <= 2.0.87.1.

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 Ads by WPQuads WordPress plugin allows unauthenticated or lower-privileged users to access functionality or data beyond their intended permissions due to incorrectly configured access control security levels. This is likely an Insecure Direct Object Reference (IDOR) or improper permission check in the plugin's administrative or user-facing features.

MitigationUpdate Ads by WPQuads to the latest version that patches this authorization flaw, or implement proper capability checks and nonce validation on all sensitive plugin actions to enforce role-based access control.

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. Identify WPQuads plugin installation
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Ads by WPQuads' or 'WPQuads', or check the /wp-content/plugins/ directory for a folder named 'wp-quads' or similar. Review the plugin files (typically plugin.php or index.php in the plugin folder) to find the version number in the plugin header comment.
    Affected if The plugin is installed and active on the WordPress site.
  2. Determine installed plugin version
    Open the main plugin file in a code editor or view it via file manager/FTP. Look for the version string in the plugin header: 'Version: X.X.X' or check readme.txt for the 'Stable tag' entry.
    Affected if Unable to determine version, or version is below the patched release that addresses CVE-2025-30855.
  3. Verify user role permissions on plugin admin pages
    Create or use a test WordPress user account with a lower privilege level (e.g., Editor, Author, Contributor, or Subscriber). Attempt to access WPQuads plugin settings pages directly via URL (typically under /wp-admin/admin.php?page=wpquads* or similar admin paths) without administrator credentials.
    Affected if Lower-privileged users can access or modify plugin settings, ad configurations, or data that should require administrator-level capabilities.
  4. Inspect plugin capability checks
    Review the plugin source code for action/filter hooks related to admin functionality (admin_init, wp_ajax_* actions, REST API endpoints). Check if functions like current_user_can(), check_admin_referer(), or nonce verification are properly implemented before sensitive operations.
    Affected if Plugin actions execute without proper current_user_can() capability checks or without valid nonce validation, allowing unauthorized access.
  5. Test for unauthenticated access to plugin features
    Attempt to access plugin-related AJAX actions or REST endpoints using a logged-out browser or curl request without authentication cookies. Check if the plugin responds to unauthenticated requests on wp_ajax or wp_ajax_nopriv hooks.
    Affected if Plugin responds to unauthenticated (not logged in) requests on AJAX or REST endpoints that perform privileged operations.

A user is affected if the WPQuads plugin is installed and either the version is unpatched or lower-privileged/unauthenticated users can access plugin administrative functions or data beyond their intended permissions.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update Ads by WPQuads to the latest version that patches this authorization flaw, or implement proper capability checks and nonce validation on all sensitive plugin actions to enforce role-based access control.

Recommended fix Moderate confidence

Upgrade to the latest available version of Ads by WPQuads (check wordpress.org for current stable release, which should be newer than 2.0.87.1)

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Locate 'Ads by WPQuads' plugin
  4. Check the current installed version (should be <= 2.0.87.1)
  5. Click 'Update now' if an update is available, or manually download the latest version from wordpress.org and upload via Plugins > Add New > Upload Plugin
  6. After update, verify the new version number in the Plugins list
  7. Test that ad display functionality works correctly
Caveat Review plugin settings after upgrade as minor configuration changes may occur between versions
