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
The The Coupon Affiliates – Affiliate Plugin for WooCommerce plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.16.7.1. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. This functionality is also vulnerable to Reflected Cross-Site Scripting. The Cross-Site Scripting was patched in version 5.16.7.1, while the arbitrary shortcode execution was patched in 5.16.7.2.

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.

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

  2. Determine installed plugin version
    In WordPress admin > Plugins > Installed Plugins, find 'Coupon Affiliates' and read the version number from the plugin description. Alternatively, check the main plugin file header in wp-content/plugins/coupon-affiliates/coupon-affiliates.php for the 'Version' comment
