CVE-2026-15296: Cservit Affiliate-Toolkit – Multi-Network Affiliate & Amazon Product Display

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The affiliate-toolkit – WP Affiliate Plugin with Amazon plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'atkp_product' shortcode in all versions up to, and including, 3.7.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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. This is a bypass to CVE-2024-10227.
