CVE-2026-2595
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 · uneditedThe Quads Ads Manager for Google AdSense plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.0.98.1 due to insufficient input sanitization and output escaping of multiple ad metadata parameters. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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 · high confidenceThe Quads Ads Manager for Google AdSense WordPress plugin is vulnerable to Stored Cross-Site Scripting (XSS) in versions up to 2.0.98.1. Authenticated users with Contributor-level access and above can inject arbitrary JavaScript through insufficiently sanitized ad metadata parameters.

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.
-
Verify Quads Ads Manager plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Quads Ads Manager for Google AdSense' or check the plugin files in wp-content/plugins/quads/ directory for the main plugin file containing the version numberAffected if Plugin is not installed or not found

-
Check for stored XSS in ad metadataReview any custom ad configurations or ad metadata that may have been saved through the plugin settings. Access the plugin settings panel (Quads > Settings or similar) and examine any ad unit configurations, custom ad parameters, or metadata fields where user input was storedAffected if Suspicious script tags, javascript: handlers, or HTML attributes found in ad metadata fields indicating potential compromise
