Technical details
StarRocks has a privilege-checking gap in the DROP MATERIALIZED VIEW statement handler. Modern (asynchronous) materialized views are stored as MaterializedView objects and properly routed through the AuthorizerStmtVisitor for privilege validation. However, legacy synchronous materialized views are stored as rollup indices on OlapTable objects; when dropped, the code path bypasses authorization and directly calls AlterJobMgr.processDropMaterializedView and MaterializedViewHandler, neither of which perform authorization checks. Any authenticated user can therefore drop a legacy synchronous materialized view without holding any grant on the view, base table, or database. The vulnerability requires authentication but no special privileges or user interaction.
