CVE-2026-44761 in Commerce Cloud
Summary
by MITRE • 07/14/2026
SAP Commerce Cloud could retain a sample OAuth2 client with publicly documented sample credentials originating from sample configuration provided in SAP Help Portal documentation. If left unchanged, an unauthenticated attacker could use these well-known credentials to obtain a valid access token and invoke certain APIs to read and modify data. Successful exploitation results in high impact on confidentiality and integrity, with no impact on availability.

This vulnerability represents a critical security flaw in SAP Commerce Cloud systems where default sample configurations contain hard-coded OAuth2 client credentials that are publicly available in SAP Help Portal documentation. The issue stems from the inclusion of well-known client identifiers and secrets within sample code and configuration files that administrators fail to properly secure or remove during production deployment. This creates an inherent risk where attackers can exploit these documented credentials to authenticate against the system without requiring any valid user accounts or authentication mechanisms.
The technical implementation flaw occurs when SAP Commerce Cloud installations retain default sample configurations that include OAuth2 client credentials with predefined values such as client_id and client_secret combinations. These credentials are typically designed for demonstration purposes but are not properly secured in production environments, allowing attackers to leverage them for unauthorized access. The vulnerability aligns with CWE-798 which addresses the use of hard-coded credentials and CWE-312 which covers the exposure of sensitive information through cleartext storage or transmission.
The operational impact of this vulnerability is significant as it enables unauthenticated attackers to obtain valid OAuth2 access tokens through legitimate authentication flows, bypassing normal user authentication requirements. Once authenticated, attackers can invoke various APIs within the SAP Commerce Cloud platform to read and modify sensitive data including customer information, product catalogs, order details, and other business-critical data. This leads to high impact on both confidentiality and integrity as attackers can exfiltrate sensitive information and alter system data without detection. The absence of availability impact suggests that while the system remains operational, the data within it becomes compromised through unauthorized modifications.
Organizations should implement immediate mitigation strategies including the complete removal or replacement of sample OAuth2 client credentials in production environments, implementation of automated security scanning to identify hardcoded credentials, and enforcement of secure configuration management practices. System administrators must ensure that all default configurations are reviewed and secured during deployment phases, with specific attention to OAuth2 client settings and credential management. The use of principle of least privilege should be enforced where even authenticated users have limited access to sensitive data and operations. This vulnerability demonstrates the importance of proper security hardening and configuration management practices as outlined in industry standards such as NIST SP 800-53 controls for system and information integrity, and aligns with ATT&CK technique T1566 which covers credential harvesting through social engineering and default credentials exploitation. Regular security assessments and penetration testing should be conducted to identify similar hardcoded credentials across all system components and ensure that production environments are properly secured against such default configuration vulnerabilities.
