CVE-2025-13859

Impact

The AffiliateX – Amazon Affiliate Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_customization_settings AJAX action in versions 1.0.0 to 1.3.9.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to store arbitrary JavaScript that executes whenever an AffiliateX block renders on the site.
