CVE-2026-0486 is a vulnerability classified under CWE-862 (Missing Authorization) that affects ABAP based SAP systems. The issue arises because a remote-enabled function module within these SAP systems does not enforce proper authorization checks for authenticated users. This flaw allows users with valid credentials to access system information that should otherwise be restricted. The vulnerability impacts specific SAP versions, including ST-PI 2005_1_700, 2008_1_710, 740, and 758. The attack vector is network-based, requiring the attacker to have authenticated access but no additional user interaction. The vulnerability leads to unauthorized disclosure of system information, which can be leveraged by attackers for reconnaissance or to facilitate further attacks. However, it does not affect the integrity or availability of the system. The CVSS v3.1 base score is 5.0, reflecting a medium severity level due to the limited confidentiality impact and the requirement for authentication. No public exploits have been reported yet, but the vulnerability's presence in widely used SAP systems makes it a concern for organizations relying on these platforms. SAP has not yet published patches, so organizations must rely on compensating controls until updates are available.

For European organizations, the primary impact of CVE-2026-0486 is the unauthorized disclosure of sensitive system information within SAP environments. This can lead to increased risk of targeted attacks, as attackers may gain insights into system configurations, user roles, or other internal details that facilitate privilege escalation or lateral movement. While the vulnerability does not compromise data integrity or system availability, the leakage of system information can undermine overall security posture and compliance with data protection regulations such as GDPR. Organizations in sectors heavily reliant on SAP, including manufacturing, finance, and logistics, may face operational risks if attackers exploit this vulnerability to gather intelligence. Additionally, the requirement for authenticated access means insider threats or compromised credentials could be leveraged to exploit this flaw. The medium severity rating indicates a moderate risk level, but given SAP's critical role in enterprise resource planning across Europe, the impact could be significant if combined with other vulnerabilities or attack vectors.

1. Conduct a thorough review of user access rights within SAP systems to ensure that only authorized personnel have access to sensitive function modules. 2. Implement strict authentication and session management policies to reduce the risk of credential compromise. 3. Monitor SAP system logs and network traffic for unusual access patterns or attempts to invoke remote-enabled function modules unexpectedly. 4. Apply SAP security notes and patches promptly once they become available for the affected versions. 5. Use SAP's built-in authorization concepts to enforce the principle of least privilege, restricting access to function modules based on job roles. 6. Consider deploying network segmentation and firewall rules to limit access to SAP systems from untrusted networks. 7. Educate SAP administrators and users about the risks associated with this vulnerability and the importance of secure credential management. 8. If patching is delayed, implement compensating controls such as enhanced monitoring and temporary access restrictions to mitigate risk.
