# CVE-2026-27689: Denial of service (DOS) in SAP Supply Chain Management

- Severity: CVSS 7.7 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-03-10 · Updated: 2026-03-10

## Affected

- SAP\_SE SAP Supply Chain Management: SCMAPO 713, 714, S4CORE 102, 103, 104, S4COREOP 105, 106, 107, 108, 109, SCM 700, 701, 702, 712

## Description

Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition that impacts availability, while confidentiality and integrity remain unaffected.
