From 3904f66dbc7c79b3c762fc21d31402f1af0f3ff8 Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Tue, 22 Jul 2025 23:11:33 +0000 Subject: [PATCH 1/9] feat: implement wildcard validation for SQL security (BUS-1487) - Add BlockedWildcardUsage error variant to SqlAnalyzerError enum - Enhance process_select_item to validate wildcards against physical tables - Block SELECT * and qualified wildcards on physical database tables - Allow wildcards on CTEs and derived tables - Add comprehensive tests for all wildcard validation scenarios - Maintain backward compatibility with legitimate query patterns This security enhancement prevents bypassing column-level permissions through wildcard queries on physical database tables while preserving functionality for CTEs and other legitimate use cases.
