## Technical details

This is an authorization bypass vulnerability (insufficient access control checks) in the Manage Bank Chains application module of SAP S/4HANA. The vulnerability exists in functionality that handles delete operations on specific business entities. An attacker with low-level privileges can craft specially-crafted requests that bypass authorization validation, allowing deletion of entries outside their permitted scope. The attack vector is network-based and does not require special user interaction or elevated privileges. Confidentiality and integrity are largely preserved, with impact limited to availability through unauthorized data deletion.
