CVE-2026-76969Network attack vector

Unauthenticated credential disclosure and tenant data destruction

Published Sep 8, 2026 · Updated Sep 8, 2026

Insufficient credential protection in SAP CAP applications using @sap/cds-mtxs 4.0.2 and earlier allows remote attackers to obtain credentials. SAP states only that the library performs insufficient checks on unspecified functionality and has not disclosed the request handler or omitted validation. Exposure requires a multitenant CAP application with extensibility enabled; leaked credentials let remote attackers replace or delete tenant data.
