CVE-2025-11741 is an authorization bypass vulnerability categorized under CWE-639, affecting the WPC Smart Quick View for WooCommerce plugin for WordPress in all versions up to and including 4.2.5. The vulnerability exists due to insufficient restrictions on the 'woosq_quickview' AJAX endpoint, which is designed to provide quick product views on WooCommerce-powered sites. This endpoint fails to properly verify whether the requesting user is authorized to view certain posts, including those marked as password protected, private, or draft. As a result, unauthenticated attackers can craft requests to this endpoint and retrieve sensitive product information that should be inaccessible. The vulnerability does not require any user interaction or authentication, making it remotely exploitable over the network with low complexity. The CVSS v3.1 score is 5.3 (medium), reflecting the limited impact on confidentiality without affecting integrity or availability. No known public exploits have been reported yet, but the exposure of sensitive product data could lead to competitive intelligence leaks or other privacy concerns. The vulnerability affects all versions of the plugin up to 4.2.5, and no official patches were linked at the time of publication, indicating that users must monitor vendor updates closely. The root cause is a failure to enforce proper authorization checks on user-controlled keys used to fetch product data via AJAX, a common pitfall in web application security.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the WPC Smart Quick View plugin, this vulnerability poses a risk of unauthorized disclosure of sensitive product information. This could include unreleased products, pricing strategies, or other confidential data intended only for authorized users. Such information exposure can undermine competitive advantage, damage brand reputation, and potentially violate data protection regulations if personal or sensitive customer data is indirectly exposed. Although the vulnerability does not allow modification or deletion of data, the confidentiality breach alone can have significant business impacts. The ease of exploitation without authentication increases the risk of automated scanning and data harvesting by malicious actors. Given the widespread use of WooCommerce in Europe, particularly in countries with mature e-commerce markets, the potential scale of impact is considerable. Organizations may also face compliance challenges under GDPR if the exposed data includes personal information or if the breach leads to further exploitation.

1. Monitor the vendor’s official channels for an official patch and apply it immediately upon release. 2. In the interim, restrict access to the 'woosq_quickview' AJAX endpoint by implementing web application firewall (WAF) rules that limit requests to trusted IP ranges or require authentication. 3. Disable or remove the WPC Smart Quick View plugin if it is not essential to business operations. 4. Conduct an audit of all WooCommerce plugins to identify vulnerable versions and ensure timely updates. 5. Implement strict access controls on WordPress content, ensuring that private, draft, or password-protected posts are not accessible via AJAX endpoints without proper authorization. 6. Employ security monitoring and anomaly detection to identify unusual access patterns to the AJAX endpoint. 7. Educate development and security teams about secure coding practices related to authorization checks on user-controlled inputs. 8. Review server and application logs regularly to detect potential exploitation attempts.
