Technical Details for CVE-2026-0494
Vulnerability Analysis
This vulnerability represents an information exposure flaw in the SAP Fiori Intercompany Balance Reconciliation application. The application fails to properly enforce access controls under certain conditions, allowing authenticated users to view information that should be restricted based on their authorization level. While the integrity and availability of the application are not impacted, the confidentiality breach could expose sensitive financial reconciliation data between company entities.
The vulnerability requires the attacker to be authenticated with low-level privileges, and no user interaction is required for exploitation. The attack can be conducted remotely over the network, making it accessible to any authenticated user with network access to the SAP Fiori application.
Root Cause
The root cause of CVE-2026-0494 is classified under CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere. This indicates that the SAP Fiori Intercompany Balance Reconciliation application contains flawed authorization logic that fails to properly validate user permissions before displaying certain information. The application exposes sensitive system or business information to users who should not have access to it based on their assigned roles and permissions.
Attack Vector
The attack is network-based and requires low-privilege authentication. An attacker with valid credentials to the SAP Fiori application can exploit this vulnerability without requiring any special privileges or user interaction. The attacker would access the Intercompany Balance Reconciliation application and navigate to or request specific resources that should be restricted, but due to the authorization flaw, are improperly exposed.
The exploitation mechanism involves leveraging the application's failure to enforce proper access controls when handling requests for reconciliation data. Technical details regarding specific exploitation steps should be obtained from SAP Note #3655227.
