CVE-2026-0511 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the SAP Fiori App Intercompany Balance Reconciliation module. The flaw arises because the application fails to enforce proper authorization checks for authenticated users, allowing them to escalate privileges beyond their assigned roles. This means that a user with limited access rights can perform actions or access data reserved for higher-privileged users, compromising confidentiality and integrity of financial reconciliation data. The vulnerability affects a broad range of SAP Fiori versions (UIAPFI70 500 through 902) and S4CORE versions 102 through 108, indicating a widespread impact across SAP’s enterprise resource planning ecosystem. The CVSS 3.1 base score is 8.1, reflecting high severity due to network attack vector, low attack complexity, and no requirement for user interaction, although some privileges are needed to exploit. The scope remains unchanged, but the impact on confidentiality and integrity is high, as unauthorized users can access or alter sensitive intercompany financial data. Availability is not affected. No patches are currently linked, and no known exploits have been reported in the wild, but the vulnerability’s nature makes it a significant risk for organizations relying on SAP for financial operations. The missing authorization check is a critical security oversight that could facilitate insider threats or external attackers leveraging compromised credentials to escalate privileges and manipulate financial records.

For European organizations, the impact of CVE-2026-0511 is substantial, especially for those operating multinational corporations with complex intercompany financial transactions managed via SAP Fiori. Unauthorized privilege escalation can lead to exposure or manipulation of sensitive financial data, undermining data confidentiality and integrity. This could result in financial fraud, regulatory non-compliance (e.g., GDPR, SOX), and reputational damage. Since SAP is widely used across Europe in industries such as manufacturing, finance, and logistics, the vulnerability poses a risk to critical business processes. Although availability is not impacted, the breach of confidentiality and integrity could disrupt financial reporting and auditing processes, potentially triggering legal and financial penalties. The lack of known exploits currently provides a window for proactive mitigation, but the ease of exploitation and network accessibility mean attackers could develop exploits rapidly once details become public.

Organizations should immediately review and restrict user privileges within SAP Fiori to the minimum necessary, ensuring that only trusted users have access to the Intercompany Balance Reconciliation app. Implement strict role-based access controls and conduct audits of user permissions to detect any anomalies. Monitor SAP system logs for unusual access patterns or privilege escalations. Since no official patches are currently available, consider deploying compensating controls such as network segmentation to limit access to SAP Fiori interfaces and enforce multi-factor authentication for all SAP users. Engage with SAP support channels to obtain any forthcoming patches or security advisories. Additionally, conduct regular security assessments and penetration testing focused on SAP applications to identify and remediate authorization weaknesses. Train SAP administrators and users on the risks of privilege escalation and the importance of adhering to security policies.
