Administrator database disclosure via whitespace filter bypass
Published Dec 23, 2025 · Updated Dec 23, 2025
SQL injection in RuoYi 4.7.9 and earlier allows remote authenticated users to read database contents through the createTable endpoint. SqlUtil.filterKeyword blocks select only when followed by a space, so a vertical-tab separator bypasses the blacklist before the SQL is executed. Administrator access is required; the demonstrated Boolean oracle extracts database values, including credentials and configuration.
