CVE-2026-76960 in S4HANA
Summary
by MITRE • 09/08/2026
SAP S/4HANA Finance (Advanced Payment Management) does not perform sufficient Cross-Site Request Forgery protection on certain requests, due to this an attacker with low privileges could craft a malicious link or page. If an authenticated victim interacts with it, unintended actions could be triggered on the web server on their behalf. This results in a low impact on confidentiality and integrity. There is no impact on availability.

The vulnerability identified within SAP S/4HANA Finance Advanced Payment Management represents a classic Cross-Site Request Forgery (CSRF) flaw, specifically categorized under CWE-352: Using GET with Side Effects or more broadly as insufficient CSRF protection in web applications. This security deficiency arises from the application's failure to implement adequate verification mechanisms for state-changing HTTP requests, such as those used to initiate payments or modify financial configurations. In a properly secured system, server-side validation should ensure that each request originates from an authorized source and includes unique, unpredictable tokens that bind the session to the specific user context. The absence of these controls allows external entities to forge valid-looking requests on behalf of authenticated users without their knowledge or consent.
From a technical perspective, the operational impact stems directly from this lack of validation. An attacker with low privileges can construct malicious HTML pages or links containing pre-filled forms that mimic legitimate administrative actions within the SAP interface. When an administrator or user who is currently logged into the S/4HANA system visits the crafted page or clicks the link, their browser automatically includes session cookies and authentication headers in the request due to standard HTTP behavior. The server processes this forged request as if it were initiated by the legitimate user, thereby executing unintended actions such as transferring funds, changing payment methods, or altering financial settings. This mechanism exploits the trust that web browsers place in a site's domain when handling authenticated sessions.
The impact on confidentiality and integrity is assessed as low because while an attacker can trigger specific transactions or configuration changes, they typically cannot directly exfiltrate sensitive data from the server through this vector alone. The primary risk lies in the potential for financial loss due to unauthorized payments or operational disruption caused by incorrect system configurations. However, since availability remains unaffected, the core infrastructure continues to operate normally despite these malicious actions. This distinction is crucial for prioritizing remediation efforts and understanding that while integrity of business logic is compromised, service uptime is not directly threatened by this specific flaw.
To mitigate this vulnerability, SAP recommends applying the latest security patches or notes provided in their official support portal which address CSRF token implementation gaps. Administrators should also ensure that all sensitive endpoints require unique anti-CSRF tokens generated per session and validated upon submission. Additionally, implementing strict SameSite cookie attributes can prevent browsers from sending cookies with cross-site requests, providing an additional layer of defense against such attacks. Regular security audits focusing on state-changing operations are essential to identify similar weaknesses across the application landscape.
This vulnerability aligns with MITRE ATT&CK technique T1566.002: Spearphishing Link, where attackers lure victims into visiting a malicious site that performs unauthorized actions within an authenticated session. It also relates to CWE-347: Improper Verification of Cryptographic Signature if the application relies on signatures without proper context binding, though CSRF is primarily about request origin verification rather than cryptographic integrity in this specific context. Organizations must treat such flaws with urgency as they bypass authentication controls by leveraging existing valid sessions, effectively allowing low-privilege users to perform high-impact actions through social engineering or web-based traps.
