CVE-2026-58230: Sap approuter open redirect vulnerability

Sap · Approuter

SAP Approuter does not sufficiently validate certain token content under specific configurations. An unauthenticated attacker could send a specially crafted token to cause sensitive credential material to be sent to an attacker-controlled destination. The attack complexity is high due to non-default preconditions required in the target environment. This results in a high impact on confidentiality and a low impact on integrity and availability.
