Summary

SAP ABAP Platform from KERNEL 7.93 and from 9.16 is affected. A regression caused by an API change reintroduces a previously fixed authorization weakness (CWE-1188), so the session manager can be opened in single transaction mode, including from FLP. A low-privileged remote attacker can use specially crafted requests to bypass restrictions, with high impact on integrity and low impact on confidentiality.
