CVE-2026-103888: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in wpclever WPC Smart Quick View for WooCommerce
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.
AI Analysis
Technical Summary
CVE-2026-103888 describes a reflected cross-site scripting vulnerability in the WPC Smart Quick View for WooCommerce plugin for WordPress. The flaw arises from insufficient sanitization and escaping of the 'woosq-redirect' parameter in all versions up to 4.4.0. When the WooCommerce setting 'redirect to cart after add to cart' is enabled, the filter processing this parameter executes, allowing an attacker to inject malicious scripts. The auto-open quick-view mechanism means that merely loading a crafted URL can trigger script execution without further user action.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to execute arbitrary scripts in the context of the victim's browser session. This can lead to information disclosure, session hijacking, or other client-side impacts. The vulnerability requires the WooCommerce 'redirect to cart after add to cart' option to be enabled, which controls the execution of the vulnerable filter. There is no indication of direct server-side impact or denial of service.
Mitigation Recommendations
No official patch or fix is currently documented for this vulnerability. Users should verify the vendor advisory for updates. As a temporary mitigation, disabling the WooCommerce 'redirect to cart after add to cart' option may prevent the vulnerable filter from executing. Additionally, avoid using the auto-open quick-view feature until a fix is available. Monitor vendor channels for an official patch and apply it promptly once released.
