CVE-2025-29006 is a Missing Authorization vulnerability (CWE-862) identified in the centangle Direct Checkout for WooCommerce Lite plugin, affecting versions up to 1.0.3. This vulnerability arises because certain functionality within the plugin is not properly constrained by Access Control Lists (ACLs), allowing unauthorized users to access or invoke functions that should require specific permissions. The plugin is designed to streamline the checkout process on WooCommerce-based e-commerce sites by enabling direct checkout capabilities. Due to the lack of proper authorization checks, an attacker can potentially exploit this flaw remotely (network vector) without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact primarily affects the integrity of the system, as unauthorized actions could be performed that may alter order processing or checkout workflows, but confidentiality and availability impacts are not indicated. The CVSS score of 5.3 reflects a medium severity level, highlighting a moderate risk. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in March 2025 and published in June 2025. Given the plugin's role in e-commerce transactions, exploitation could lead to unauthorized manipulation of checkout processes, potentially resulting in fraudulent orders, bypassing payment steps, or other integrity-related issues within the affected WooCommerce stores.

For European organizations operating e-commerce platforms using WooCommerce with the centangle Direct Checkout Lite plugin, this vulnerability poses a tangible risk to transactional integrity. Attackers exploiting this flaw could manipulate checkout processes, potentially bypassing payment verification or altering order details, leading to financial losses, reputational damage, and customer trust erosion. Given the widespread adoption of WooCommerce across Europe, especially among small and medium-sized enterprises (SMEs) in retail and services sectors, the impact could be significant. Additionally, compromised checkout integrity may lead to regulatory compliance issues under GDPR if customer data or transaction records are improperly handled or altered. The absence of authentication requirements for exploitation increases the threat surface, making automated or mass exploitation attempts feasible. However, the lack of known exploits and the medium severity rating suggest that immediate widespread impact is limited but should not be underestimated, especially as threat actors often target e-commerce platforms.

1. Immediate assessment of all WooCommerce installations to identify the presence of the centangle Direct Checkout Lite plugin and its version. 2. Since no official patch is currently available, implement temporary access restrictions at the web server or application firewall level to limit access to the vulnerable plugin endpoints, especially from untrusted networks. 3. Employ strict monitoring and logging of checkout-related activities to detect anomalous or unauthorized actions indicative of exploitation attempts. 4. Consider disabling or replacing the Direct Checkout Lite plugin with alternative, well-maintained plugins that have robust authorization controls until a patch is released. 5. Engage with the plugin vendor or community to obtain updates or security advisories and apply patches promptly once available. 6. Conduct security awareness and training for site administrators to recognize and respond to suspicious checkout behavior. 7. Review and harden WooCommerce and WordPress user roles and permissions to minimize potential abuse vectors. 8. Implement Web Application Firewall (WAF) rules tailored to detect and block exploitation patterns targeting this vulnerability.
