CVE-2026-44745: SAP Approuter has an Open Redirect vulnerability

July 14, 2026 (updated September 1, 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.
