Security readout for executives and security teams
Plain-English summary
CVE-2026-0491 is a critical SAP Landscape Transformation flaw. An attacker who already has admin privileges could abuse an RFC-exposed function module to inject ABAP code or OS commands, bypass authorization checks, and potentially take full control of the SAP system.
Executive priority
Treat as urgent for SAP environments using Landscape Transformation. Although admin privileges are required, compromise of such an account could lead to full system compromise affecting business-critical data, operations, and trust in SAP-controlled processes.
Technical view
The vulnerability is CWE-94 code injection in SAP Landscape Transformation DMIS versions 2011_1_700, 2011_1_710, 2011_1_730, 2011_1_731, 2018_1_752, and 2020. CVSS 3.1 is 9.1: network reachable, low complexity, high privileges required, no user interaction, scope changed, high CIA impact.
Likely exposure
Exposure is likely limited to organizations running affected SAP Landscape Transformation DMIS versions with RFC access paths reachable by privileged users or compromised admin accounts. The source states default status is unaffected outside listed versions.
Exploitation context
The CVE record does not report active exploitation, and this CVE is not marked KEV in the provided data. Exploitation requires high privileges, but impact is severe because the flaw can bypass authorization checks and function like a backdoor.
Researcher notes
Evidence comes from the CVE record and SAP references. Public details are limited; no exploit status or specific patch contents are provided in the bundle. Avoid assuming exposure beyond the listed DMIS versions and confirm remediation through SAP Note 3697979.
Mitigation direction
- Review SAP Note 3697979 and SAP Security Patch Day guidance.
- Apply SAP-provided corrections for affected DMIS versions if available.
- Restrict RFC access to trusted administrative users only.
- Audit SAP admin accounts for compromise or excessive privilege.
- Monitor SAP systems for unauthorized ABAP or OS command activity.
Validation and detection
- Inventory SAP Landscape Transformation and DMIS component versions.
- Confirm whether any listed affected DMIS version is installed.
- Review RFC-exposed function modules and administrative access paths.
- Check whether SAP Note 3697979 corrections are applied.
- Review logs for suspicious privileged RFC activity.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
