CVE-2026-24321 is a vulnerability identified in SAP Commerce Cloud, specifically affecting versions HY_COM 2205, COM_CLOUD 2211, and 2211-JDK21. The issue arises because multiple API endpoints are exposed to unauthenticated users, allowing them to submit requests and retrieve sensitive personal information that should not be publicly accessible. This vulnerability is classified under CWE-359, which pertains to the exposure of private information to unauthorized actors. The technical root cause is the lack of proper access controls on certain API endpoints, which bypass authentication and authorization checks. The vulnerability has a CVSS v3.1 base score of 5.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) shows that the attack can be performed remotely over the network without any privileges or user interaction, impacting confidentiality only. There is no impact on integrity or availability, which limits the overall damage. No patches or exploits are currently reported, but the exposure of personal data can lead to privacy violations and regulatory non-compliance. The vulnerability affects the confidentiality of personal data processed or stored by SAP Commerce Cloud, which is widely used in e-commerce platforms globally. The issue requires immediate attention to prevent unauthorized data disclosure.

For European organizations, the exposure of private personal information through SAP Commerce Cloud APIs can lead to significant privacy breaches, potentially violating GDPR and other data protection regulations. Even though the impact on confidentiality is rated as low, unauthorized access to personal data can result in reputational damage, regulatory fines, and loss of customer trust. Since SAP Commerce Cloud is used by many enterprises for online retail and customer management, the leakage of sensitive customer data could affect business operations and customer relationships. The lack of impact on integrity and availability means that system operations remain stable, but the confidentiality breach alone is critical in the context of stringent European data privacy laws. Organizations in sectors such as retail, finance, and telecommunications that rely on SAP Commerce Cloud are particularly vulnerable. The potential for automated exploitation without authentication increases the risk of mass data harvesting by malicious actors.

European organizations should immediately audit their SAP Commerce Cloud deployments to identify exposed API endpoints accessible without authentication. Implement strict access control mechanisms to ensure all sensitive API endpoints require proper authentication and authorization. Employ API gateways or web application firewalls (WAFs) to monitor and restrict suspicious API traffic. Regularly update SAP Commerce Cloud to the latest patched versions once SAP releases fixes addressing this vulnerability. Conduct thorough penetration testing focused on API security to detect similar exposure issues. Implement logging and alerting for unusual API access patterns to enable rapid incident response. Review and minimize the amount of personal data accessible through APIs, applying the principle of least privilege. Additionally, organizations should review their data protection policies and ensure compliance with GDPR requirements regarding personal data exposure and breach notification.
