- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-10-13 · Updated: 2026-10-13

## Affected

- SAP\_SE SAP ABAP Platform: KERNEL 7.93, 9.16

## Description

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.
