CVE-2026-44769 in S4HANA
Summary
by MITRE • 07/14/2026
SAP S/4HANA application Project Management (PPM-PRO) allows an attacker with high privileges to execute crafted database queries, exposing the backend database. This results in low impact on confidentiality, with no impact on integrity and availability of the application.

This vulnerability exists within SAP S/4HANA's Project Management module where an attacker with high privileges can manipulate database query execution through crafted inputs. The flaw stems from insufficient input validation and improper parameter handling within the application's database interaction layer, allowing maliciously constructed queries to be executed against the backend database system. The vulnerability is classified as a database injection issue that operates at the application level rather than the network level, making it particularly dangerous when combined with elevated privilege access.
The technical implementation of this vulnerability involves the application's failure to properly sanitize user inputs before incorporating them into database query structures. When high-privilege users submit crafted data through the project management interfaces, the system processes these inputs without adequate validation mechanisms, potentially allowing attackers to construct malicious SQL or NoSQL queries that traverse the application's database layer. This represents a classic privilege escalation scenario where existing elevated access is leveraged to gain unauthorized data exposure from the backend systems.
From an operational impact perspective, while the vulnerability results in low confidentiality impact, it still constitutes a significant security risk within enterprise environments where SAP S/4HANA systems process sensitive business and financial data. The exposure of backend database information could provide attackers with detailed insights into project management data structures, including resource allocations, timelines, budget allocations, and other confidential business information. The absence of integrity and availability impact suggests that while data disclosure is possible, the system's core functionality remains unaffected, though this does not diminish the severity of the information exposure.
The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws in database query construction. This classification places it within the broader category of injection vulnerabilities that have been consistently ranked among top cybersecurity threats by organizations like OWASP and NIST. The attack vector requires high privilege access, indicating that the vulnerability is more likely to be exploited by insiders or through credential compromise rather than external attacks against publicly exposed interfaces.
Mitigation strategies should focus on implementing comprehensive input validation and parameterized query execution throughout the application's database interaction layers. SAP recommends applying the latest security patches and updates to address known vulnerabilities in the S/4HANA platform, particularly those related to Project Management modules. Organizations should also implement strict access controls and privilege management policies to minimize the potential impact of such vulnerabilities, ensuring that only authorized personnel have elevated privileges within the system. Additionally, database monitoring and logging mechanisms should be enhanced to detect anomalous query patterns that may indicate exploitation attempts, aligning with ATT&CK framework techniques related to credential access and defense evasion.
