Unauthenticated privilege escalation to arbitrary permissions
Published Dec 12, 2023 · Updated Feb 25, 2026
Privilege escalation in SAP BTP Security Services Integration Library sap-xssec before 4.1.0 allows remote attackers to gain arbitrary permissions. SAP has not published the vulnerable function, exposed dangerous method, or token-validation condition that handles untrusted input incorrectly. Exploitation requires an unauthenticated network request carrying an access token to an application that relies on the Python library, and it grants permissions within that application without reported service interruption.
