CVE-2026-24599 identifies a critical authorization bypass vulnerability in the XLPlugins NextMove Lite WordPress plugin, specifically affecting versions up to and including 2.23.0. The vulnerability stems from improper access control enforcement in the woo-thank-you-page-nextmove-lite component, where a user-controlled key parameter can be manipulated to bypass security restrictions. This misconfiguration allows an attacker to gain unauthorized access to functionalities or data that should be restricted, potentially leading to data leakage, unauthorized order manipulation, or privilege escalation within the e-commerce environment. The flaw does not require prior authentication or user interaction, increasing its risk profile. Although no public exploits are currently known, the vulnerability's nature and the widespread use of WordPress and its plugins in e-commerce make it a significant concern. The absence of a CVSS score necessitates a severity assessment based on the vulnerability's characteristics, which indicate a high impact on confidentiality and integrity with relatively straightforward exploitation. The vulnerability affects all installations running vulnerable versions of NextMove Lite, a plugin commonly used to manage WooCommerce order thank-you pages, making it relevant to organizations relying on this plugin for order processing and customer interaction.

For European organizations, the impact of CVE-2026-24599 can be substantial, particularly for those operating e-commerce platforms using WordPress with the NextMove Lite plugin. Unauthorized access due to this vulnerability could lead to exposure of sensitive customer data, manipulation of order information, and potential disruption of order fulfillment processes. This could result in financial losses, reputational damage, and regulatory non-compliance, especially under GDPR requirements for protecting personal data. Retailers and service providers relying on WooCommerce and NextMove Lite for customer order management are at heightened risk. The vulnerability could also be leveraged as a foothold for further attacks within the network, increasing the overall threat landscape. Given the plugin’s role in order management, the integrity and availability of order data are critical, and compromise could disrupt business operations and customer trust.

European organizations should immediately audit their WordPress installations to identify the use of NextMove Lite plugin versions up to 2.23.0. Until an official patch is released, organizations should implement strict access control policies at the web server and application levels to restrict access to the affected plugin components. Employ web application firewalls (WAFs) with custom rules to detect and block requests containing suspicious user-controlled keys targeting the woo-thank-you-page-nextmove-lite endpoint. Regularly monitor logs for anomalous access patterns or unauthorized attempts to manipulate order pages. Organizations should also consider temporarily disabling the NextMove Lite plugin if it is not critical to operations or replacing it with alternative solutions that do not exhibit this vulnerability. Once the vendor releases a patch, prioritize its deployment and verify that access control configurations are correctly enforced. Additionally, conduct security awareness training for administrators to recognize and respond to potential exploitation attempts.
