Critical SQL Injection Vulnerability: The `QueryExecutor` directly executes SQL query strings (`duckdb_query(conn, query.c_str(), &result)`) which are constructed from Mustache templates and user-provided parameters. While a `RequestValidator` attempts to prevent SQL injection using regex, this method is fundamentally insufficient and prone to bypasses, posing a severe risk. This allows malicious users to execute arbitrary SQL commands including data exfiltration, modification, or deletion. Additionally, `executeWrite` splits queries by semicolon, enabling multi-statement injection. It is recommended to use parameterized queries with prepared statements for all user-controlled inputs. Other security aspects like JWT/OIDC authentication are implemented using standard libraries (jwt-cpp, OpenSSL) which is a positive, and AWS Secrets Manager integration leverages DuckDB's secret management, but the core SQL execution flaw is critical.
