Summary: SAP has released its first security notes of 2026, headlined by a critical SQL Injection vulnerability (CVE-2026-0501, CVSS 9.9) in SAP S/4HANA Financials – General Ledger. An attacker can execute arbitrary SQL commands, potentially gaining full control over financial records and the underlying system.
Business Impact: Extreme. The General Ledger is the financial core of the enterprise. Compromise here could lead to undetected financial fraud, data manipulation, and total loss of integrity in financial reporting—posing a significant risk for publicly traded companies.
Why It Happened: The flaw involves an RFC-enabled function module that uses ABAP Database Connectivity (ADBC) without proper input validation, allowing native SQL statements to be injected.
Recommended Executive Action: Prioritize SAP Security Note #3687749 for immediate deployment. Audit all financial transactions and general ledger logs from the past 48 hours to ensure no unauthorized tampering occurred.
