SAP Business AI Platform (Approuter): improper certificate validation
Medium6.4CVE-2026-66760 · Published Aug 11, 2026 · updated Sep 8, 2026
SAP Approuter does not correctly validate client certificates in certain callback flows. An attacker with low privileges, holding a certificate from the same trusted authority with matching subject values, could bypass the identity check. This complexity makes the attack difficult to execute. Successful exploitation could allow impersonation of a trusted internal component, resulting in a high impact on integrity and a low impact on confidentiality and availability.
