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
Unauthenticated Sensitive Data Exposure in Ads by WPQuads <= 3.0.3 versions.

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

Unauthenticated sensitive data exposure vulnerability in the WordPress plugin 'Ads by WPQuads' affecting versions 3.0.3 and below. The vulnerability allows remote, unauthenticated attackers to access sensitive data without requiring any authentication credentials.

MitigationUpdate Ads by WPQuads plugin to the latest patched version immediately. If no patched version is available, consider temporarily disabling the plugin or implementing web application firewall rules to block exploitation attempts.

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 WPQuads plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for the 'wp-quads' or 'ads-by-wpquads' folder, or look for 'WPQuads' in the WordPress admin plugin list
    Affected if The plugin folder exists in the plugins directory or appears in the WordPress admin
  2. Identify the installed version
    Open the main plugin file (typically wp-quads/wp-quads.php or similar) and locate the version comment/constant at the top of the file
    Affected if The version number found is 3.0.3 or lower, or no version is declared (indicating an outdated installation)
  3. Check for publicly accessible sensitive endpoints
    Test common WPQuads AJAX or REST endpoints (such as /wp-admin/admin-ajax.php?action=quads_* or /wp-json/quads/*) without authentication using curl or a browser
    Affected if Requests to plugin-related endpoints return sensitive data without requiring login credentials
  4. Review server access logs for exploitation attempts
    Search web server logs (Apache/Nginx) for unusual requests to WPQuads-related paths, especially those containing 'quads' in the URL parameter or path
    Affected if Logs show repeated unauthenticated requests to plugin endpoints returning data that should require authentication

If the WPQuads plugin version is 3.0.3 or below and its endpoints are reachable without authentication, the environment is affected by this CVE.
