## What is CVE-2026-27689?

CVE-2026-27689 is a high-severity denial of service vulnerability in SAP_SE SAP Supply Chain Management, published on 10 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-606 (Unchecked Input for Loop Condition)
