| Bug reference | Description | Fix area | Component | Platform | | --- | --- | --- | --- | --- | | 4653635 | This update resolves an issue in SQL Server Analysis Services where Row-Level Security (RLS) filters could be skipped when combined with Object-Level Security (OLS) and Column-Level Security (CLS) in certain multi-role configurations. This only occurs under rare and contradictory setups (for example, a role granting table-level read permission while restricting all columns, combined with other similar restrictive roles). The fix ensures RLS is consistently applied in all scenarios. | Analysis Services | Analysis Services | Windows | | 4711204 | This hotfix addresses a SQL injection vulnerability in an internal backup stored procedure, that was inadvertently exposed to all users. The hotfix restricts unauthorized access and mitigates the risk by properly sanitizing input parameters. | SQL Server Engine | Management Services | Linux, Windows |
