CVE-2026-0486
📋 TL;DR
This vulnerability in SAP ABAP systems allows authenticated users to access system information without proper authorization checks. It affects SAP systems with the vulnerable remote-enabled function module. The impact is limited to information disclosure with no effect on system integrity or availability.
💻 Affected Systems
- SAP ABAP-based systems
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could access sensitive system information, potentially revealing configuration details, user data, or system architecture that could aid further attacks.
Likely Case
Authorized users exceeding their intended permissions to view system information they shouldn't have access to, potentially violating data privacy or compliance requirements.
If Mitigated
With proper authorization controls and network segmentation, impact is limited to minimal information disclosure within controlled environments.
🎯 Exploit Status
Exploitation requires authenticated access to the SAP system
