15th percentile - higher than 15% of all known CVEs

Summary

The affiliate-toolkit – Multi-Network Affiliate & Amazon Product Display plugin for WordPress up to and including 3.9.2 is vulnerable to stored cross-site scripting via the 'atkp_product_producturl' parameter due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary scripts that execute when a user accesses the page if AJAX loading is enabled and a product ID is known; on a default installation, contributor-level access is required.

Risk Assessment

An attacker can inject malicious scripts that execute in users' browsers, potentially leading to session or data theft. The risk depends on the plugin configuration and the attacker's privileges.

Recommendation

Update the plugin to a version later than 3.9.2. Consider disabling AJAX loading until updated and restricting contributor privileges.

Original NVD description (English source)

The affiliate-toolkit – Multi-Network Affiliate & Amazon Product Display plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'atkp_product_producturl' parameter in all versions up to, and including, 3.9.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation by unauthenticated attackers requires that the plugin's AJAX loading / AJAX handler option is enabled (atkp_options::get_ajax_loading_enabled() || get_ajax_handler_enabled()) and the attacker knows a product id to render. On a default installation, where that is not configured, the vulnerability requires attackers with contributor-level access and above.
