CVE-2026-89120
HIGH 7.1A 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.
Severe if exploited (CVSS 7.1), but no known exploitation and low modeled probability. Patch on a normal cadence.
