CVE-2026-103888WPC Smart Quick View for WooCommerce <= 4.4.0 - Reflected Cross-Site Scripting via 'woosq-redirect' Parameter
Medium 6.1
In plain English
A medium-severity cross-site scripting in WPC Smart Quick View for WooCommerce from wpclever. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 24% of all known vulnerabilities).
Official description
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.
