A regression caused by an API change in SAP ABAP Platform reintroduces a previously fixed authorization weakness. The session manager can be opened in single transaction mode, including from FLP. A low-privileged attacker could exploit this to bypass restrictions via specially crafted requests, resulting in high impact on integrity and low impact on confidentiality. There is no impact on availability.
