What changes

Fixes 2 changes

Analysis Services

For: SQL Server Analysis Services deployments with the described multi-role configurations

  • In rare, contradictory multi-role setups, Row-Level Security filters are consistently applied instead of being skipped.1
    Addresses cases where Row-Level Security (RLS) filters could be skipped when combined with Object-Level Security (OLS) and Column-Level Security (CLS).

Management Services

For: SQL Server installations on Linux or Windows

  • Unauthorized access to an internal backup stored procedure is restricted, mitigating the risk of SQL injection.2
    The hotfix correctly sanitizes input parameters for the internal backup stored procedure, which was inadvertently exposed to all users. Applies to Linux and Windows.
