Authenticated SQL injection via blacklist-bypassing subqueries

Published Feb 2, 2026 · Updated Feb 2, 2026

SQL injection in JeecgBoot 3.9.0 Online Report API allows remote authenticated users to read or alter database data via keyword. The loadDictItemByKeyword endpoint concatenates crafted subquery statements from the keyword parameter outside its SQL blacklist. A valid low-privilege account is required; successful queries can expose or modify database content and interrupt database-backed operations.
