Authenticated SQL injection via unescaped table name
Published Apr 16, 2026 · Updated Apr 16, 2026
SQL injection in FIT2CLOUD DataEase before 2.10.21 allows remote authenticated users to read database data through datasource saving. DatasourceServer.save decodes an API datasource configuration and passes its deTableName into DatasourceSyncManage, where engine providers replace a DDL template token without validating or escaping the identifier. Any authenticated user able to save an API datasource can break out of identifier quoting and execute database commands, with the demonstrated error-based path disclosing MySQL results.
