CVE-2026-24366 identifies a Missing Authorization vulnerability in the YITHEMES YITH WooCommerce Request A Quote plugin, affecting versions up to 2.46.0. This vulnerability arises from improperly configured access control mechanisms that fail to verify whether a user is authorized to perform certain actions within the plugin. Specifically, the plugin does not enforce adequate authorization checks on requests related to quote submissions or management, potentially allowing unauthenticated or unauthorized users to exploit these functionalities. The flaw is rooted in incorrect or absent validation of user permissions, which is a critical security oversight in web applications handling sensitive e-commerce operations. While no public exploits have been reported, the vulnerability could be leveraged to manipulate quote requests, access confidential pricing information, or disrupt normal business processes. The plugin is widely used in WooCommerce installations, which are prevalent in European e-commerce platforms, increasing the attack surface. The absence of a CVSS score indicates that the vulnerability is newly disclosed, but the nature of missing authorization typically results in high risk due to the direct impact on confidentiality and integrity. The vulnerability does not require user interaction but may not require authentication, increasing its exploitability. The vendor has not yet released a patch, so mitigation currently relies on configuration reviews and access restrictions.

For European organizations, this vulnerability could lead to unauthorized access to sensitive business data such as pricing and quote requests, potentially resulting in financial losses or reputational damage. Attackers might manipulate or submit fraudulent quote requests, disrupting sales workflows and customer trust. Given the widespread use of WooCommerce in Europe, especially among SMEs and large retailers, exploitation could affect a broad range of sectors including retail, manufacturing, and services. The lack of proper authorization checks could also facilitate lateral movement within compromised e-commerce environments, increasing the risk of further breaches. Additionally, regulatory compliance issues may arise if customer or business data is exposed, particularly under GDPR mandates. The impact is heightened in countries with mature e-commerce markets and stringent data protection laws, where breaches could lead to significant legal and financial penalties.

Organizations should immediately audit their WooCommerce installations to identify if the YITH WooCommerce Request A Quote plugin is in use and determine the version. Until an official patch is released, restrict access to the plugin’s quote request functionalities by implementing web application firewall (WAF) rules that block unauthorized requests targeting the plugin endpoints. Review and tighten user roles and permissions within WordPress to ensure only trusted users can access quote-related features. Monitor logs for unusual activity related to quote requests or plugin endpoints. Consider temporarily disabling the plugin if it is not critical to business operations. Stay informed about vendor updates and apply patches promptly once available. Additionally, conduct penetration testing focused on authorization controls in the e-commerce environment to detect similar weaknesses. Employ network segmentation to isolate e-commerce systems and limit potential lateral movement in case of exploitation.
