CVE-2026-109224 · Severity: high · CVSS 7.2 · Published 2026-10-16

SureCart is a WordPress plugin that enables online sales of physical products, digital downloads, subscriptions, and donations. The plugin fails to properly sanitize user comments, allowing unauthenticated attackers to inject malicious scripts that execute when other users view pages with specific SureCart components. This can lead to account compromise, payment information theft, or malware distribution to site visitors.

## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the 'comment' parameter caused by insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary JavaScript that persists on the page when the surecart-components runtime is loaded (via [sc_buy_button] shortcode) without an sc-checkout element present, which triggers an innerHTML sink in sc-cart-loader. The injected scripts execute in the context of any user viewing the affected page.
