CVE-2026-107653: SureCart Stored XSS

CVE-2026-107653 (CVSS 7.2, High) is a stored cross-site scripting vulnerability in the SureCart ecommerce plugin for WordPress, which handles physical products, digital downloads, subscriptions, donations, and payments. The comment parameter is not sufficiently sanitized, so attacker-supplied script can be stored and later run in the browser of anyone who views the affected page.

Impact

Stored XSS in a store plugin matters because the injected script can run in a logged-in administrator's session. Possible outcomes include:

  • Creating administrator accounts or changing settings through the admin's session
  • Stealing session data or redirecting visitors
  • Tampering with checkout pages in ways that could expose payment-related details

Remediation

  1. Update SureCart to the latest release available in the WordPress plugin directory, a version later than 4.9.4.
  2. Review stored content that accepts a comment value (orders, notes) for unexpected script or HTML.
  3. Use a WAF with XSS rules as a stopgap, and limit administrator browsing while logged in.
wp plugin list --name=surecart --fields=name,version,update
wp plugin update surecart

Key Takeaways

  1. CVE-2026-107653 affects SureCart 4.9.4 and earlier.
  2. The flaw is stored XSS through the comment parameter.
  3. Update the plugin and audit stored comment data.
