This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Brands for WooCommerce WordPress plugin. It allows authenticated attackers with contributor-level access or higher to inject malicious scripts via the 'style' shortcode attribute. The flaw exists due to insufficient input sanitization and output escaping in versions up to and including 3.8.8.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the Brands for WooCommerce plugin versions up to 3.8.8. Check for unauthorized script injections in pages via the 'style' shortcode attribute. Review contributor-level user activity logs for suspicious edits.
