Vulnerability in WPC Smart Quick View for WooCommerce — CVE-2026-103888

What to do now

Update WPC Smart Quick View for WooCommerce to 4.4.1 or later.

Affected versions

• Everything up to and including 4.4.0

The WPC Smart Quick View for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'woosq-redirect' parameter in all versions up to, and including, 4.4.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The WooCommerce "redirect to cart after add to cart" option must be enabled for the filter that reads the woosq-redirect parameter to execute; however, the ?quick-view= auto-open mechanism means no further user interaction beyond loading the crafted URL is required to trigger script execution.
