We advice you to follow the instructions, to resolve

According to SAP Security Advisory team a workaround does not exist. It is advisable to implement the correction as part of maintenance***.
Missing authority checks are still the most common security defect related to authorizations in custom code. Since SAP uses an explicit authorization model, an authority checks must be coded in order to be executed. If an explicit check is not coded, all users have access. This type of vulnerability not only exists in SAP standard it also exists in customer coding. Check your custom developments for vulnerabilities that pose a risk to your systems. SecurityBridge helps detect code vulnerabilities before they are implemented in production.
Risk specificationThis note has been re-released with updated ‘Solution’ information. S4/HANA Supplier Factsheet allows authenticated attacker to have access to sensitive data due to insufficient authorization check.
The B_BUPA_ADR and B_BUPA_BNK authority checks have been added in Supplier Factsheet application. On the other Hand, due to limitations in Enterprise Search Framework, controlling the search results using B_BUPA_ADR and B_BUPA_BNK is not possible. Hence, the address fields have been removed from search results. This also means that the search cannot happen using address fields.
