CVE-2026-66761Network attack vector

Authenticated service interruption via insufficient flow control

Published Aug 11, 2026 · Updated Aug 11, 2026

Resource exhaustion in SAP Business AI Platform (Approuter) before 23.0.0 allows remote authenticated users to interrupt service. SAP has not disclosed the affected function, but insufficient flow control lets requesters transmit large data volumes without consuming responses, driving unbounded memory growth. Low-privileged access is required; sustained traffic can exhaust memory and degrade availability, with no confidentiality or integrity impact.
