Summary

The SureCart plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.9.4 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.

Risk Assessment

An unauthenticated attacker can execute arbitrary JavaScript in a victim's browser, potentially leading to session theft, redirects, or other actions in the user's context. However, this requires the affected comment to appear on a post that loads the surecart-components runtime and contains no sc-checkout element.

Recommendation

Update the SureCart plugin to a version later than 4.9.4. Until then, consider disabling comments or filtering comment content.

Other vulnerabilities in SureCart WordPress Plugin

CVE-2026-18480High
The SureCart WordPress plugin before 4.6.3 does not ensure that the account affected by a customer update is the same account its permission check authorised, allowing users with a subscriber-level account to change another user's email address, including an administrator's, and take over that account via a password reset. It further allows an attacker-controlled customer record to be associated with an arbitrary user, and discloses customer identifiers and email addresses to any authenticated user, which together make the takeover reachable from a subscriber-level account alone.

Original NVD description (English source)

The SureCart – Ecommerce Made Easy For Selling Physical Products, Digital Downloads, Subscriptions, Donations, & Payments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.9.4 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. Successful execution requires the affected comment to appear on a post that loads the surecart-components runtime (e.g. via a [sc_buy_button] shortcode) and contains no sc-checkout element, as these conditions trigger the innerHTML sink in sc-cart-loader.
