Understanding the February 2026 SAP Security Updates
In February 2026, SAP released its monthly security updates addressing vulnerabilities across several SAP products. A few of these issues stand out because of their severity and the potential impact they could have on production systems if left unpatched.
Critical Vulnerabilities
CVE-2026-0488: Code Injection in SAP CRM and SAP S/4HANA (Scripting Editor)
This vulnerability affects the scripting editor component used in SAP CRM and SAP S/4HANA. An authenticated user with low privileges could exploit a flaw in how generic function modules are called. By doing so, the user could execute unauthorized critical functions, including running arbitrary SQL statements.
This is particularly serious because arbitrary SQL execution can lead to full control of the underlying database. In practical terms, that means attackers could read, modify, or delete business data, or disrupt system operations entirely. The impact spans confidentiality, integrity, and availability.
SAP has rated this vulnerability as Critical with a CVSS base score of 9.9, indicating that it requires immediate attention.
CVE-2026-0509: Missing Authorization Check in SAP NetWeaver AS ABAP and ABAP Platform
This issue exists in the authorization handling of background Remote Function Calls in SAP NetWeaver AS ABAP and the ABAP Platform. Under certain conditions, an authenticated user with basic privileges can execute background RFCs without the required S_RFC authorization.
Although this vulnerability does not directly expose confidential data, it allows unauthorized backend operations to be executed. This can lead to data manipulation, system instability, or service disruption. As a result, the integrity and availability of the system are at high risk.
SAP has classified this vulnerability as Critical with a CVSS base score of 9.6.
Other High-Severity Issues Addressed
In addition to the two critical vulnerabilities, the February 2026 Security Patch Day includes fixes for several high-severity issues, including:
- XML Signature Wrapping vulnerabilities in SAP NetWeaver AS ABAP
- Denial of service vulnerabilities in SAP Supply Chain Management
- Denial of service issues in SAP BusinessObjects BI Platform
- Missing authorization checks in SAP Solution Tools Plug-In
- Race condition vulnerabilities in SAP Commerce Cloud
- Open Redirect vulnerabilities in SAP BusinessObjects BI Platform
While these issues are generally harder to exploit than the critical ones, they still pose meaningful risks, especially in complex or exposed SAP landscapes.
Recommended Next Steps
Organizations running affected SAP components should take the following actions:
- Review the relevant SAP Security Notes to confirm whether their systems are impacted.
- Prioritize and apply patches for critical vulnerabilities as soon as possible.
- Review and restrict user access, especially for scripting and RFC-related roles.
- Monitor system activity for unusual behavior that could indicate attempted misuse.
Once vulnerabilities are publicly disclosed, they quickly become known beyond the SAP community. Prompt patching and strong access controls are the most effective ways to reduce exposure.
