CVE-2026-89113 in Commerce Cloud
Summary
by MITRE • 10/13/2026
SAP Commerce Cloud does not sufficiently validate certain user-supplied input before it is incorporated into a database query. An authenticated user could send specially crafted requests to affected functionality to inject arbitrary SQL commands. Successful exploitation could allow the user to read, modify or delete sensitive data from the application's database, resulting in a high impact on confidentiality, integrity and availability of the application.

The vulnerability identified within SAP Commerce Cloud represents a critical failure in input validation mechanisms specifically related to SQL query construction. This flaw allows an authenticated user to inject arbitrary Structured Query Language commands by supplying maliciously crafted data that is not adequately sanitized or parameterized before being incorporated into database queries. The root cause lies in the application's insufficient handling of user-supplied inputs, which suggests a reliance on string concatenation rather than prepared statements or strict type checking for certain functional areas. This lack of rigorous validation creates an opening where special characters and SQL syntax can be interpreted by the underlying database engine as executable commands rather than literal data values.
From a technical perspective, this vulnerability aligns with Common Weakness Enumeration category CWE-89, commonly known as SQL Injection. The attacker leverages their authenticated status to bypass initial access controls but exploits the subsequent lack of input sanitization within specific application functions. By manipulating query parameters, an adversary can alter the logic of database operations. This capability enables a range of malicious activities including unauthorized data exfiltration, modification of critical business records, or deletion of essential information. The ability to execute arbitrary SQL commands effectively grants the attacker control over the backend data store, bypassing application-level security controls that were designed to restrict access based on user roles and permissions.
The operational impact of this vulnerability is severe due to its high potential for compromising confidentiality, integrity, and availability. Confidentiality is compromised as attackers can extract sensitive customer information, financial records, or proprietary business logic stored in the database. Integrity is threatened because malicious actors can alter transactional data, pricing structures, or inventory levels, leading to significant operational disruptions and financial loss. Availability may be impacted if destructive commands are executed that corrupt databases or render tables inaccessible. Given that SAP Commerce Cloud handles high-volume e-commerce transactions, such a breach could result in substantial reputational damage and regulatory penalties under frameworks like GDPR or PCI-DSS due to the exposure of personally identifiable information and payment data.
In terms of threat modeling, this exploitation technique corresponds to MITRE ATT&CK techniques related to Data Injection and potentially SQL Injection via application layer attacks. Attackers typically utilize tools that automate payload generation to test for these weaknesses, often targeting login forms, search functions, or API endpoints where user input is directly mapped to database queries without proper encoding. The success of such an attack relies heavily on the attacker's ability to identify specific entry points within the commerce platform and craft payloads that evade existing web application firewalls if they are not configured with advanced SQL injection detection rules.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. Developers should immediately audit all database interaction code for instances where user input is concatenated into query strings. Replacing these patterns with parameterized queries or stored procedures ensures that the database treats inputs strictly as data, not executable code. Additionally implementing strict input validation using allow-listing techniques can prevent unexpected characters from entering the system at the application boundary. Security teams should also deploy Web Application Firewalls configured to detect and block SQL injection signatures, although this serves only as a compensating control rather than a primary fix. Regular security training for development teams on secure coding practices is essential to prevent recurrence of such vulnerabilities in future releases or customizations of the SAP Commerce Cloud environment.
