SAP Note 3797111 addresses "3797111 - [CVE-2026-89110] Broken Access Control in SAP NetWeaver Visual Composer" to prevent missing authorization check with a hot news risk for exploitation.
A workaround does exist, according to SAP Security Advisory team. It is advisable to implement the correction as monthly patch process, the team suggests.
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 specification
