SAP Approuter: open redirect

High8.1CVE-2026-44745 · Published Jul 14, 2026 · updated Sep 8, 2026

SAP Approuter does not properly validate incoming request headers during the OAuth2 login flow under certain configurations. This allows an unauthenticated remote attacker to craft a malicious link which, when clicked by a victim, could lead to unauthorized access. Successful exploitation results in a high impact to the confidentiality and integrity with no impact on the availability of the application.
