Description

DataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase SQL preview exposes DatasetDataApi.previewSql/previewSqlCheck through /de2api/datasetData/previewSql, accepts PreviewSqlDTO.sql, PreviewSqlDTO.datasourceId, and PreviewSqlDTO.isCross, then DatasetDataManage.previewSql stores decoded SQL in datasourceRequest.query and CalciteProvider.fetchResultField executes it with prepareStatement(...).executeQuery(), allowing arbitrary readable datasource tables to be queried and returned in preview responses. This issue is fixed in version 2.10.23.

• CWE-89Improper Neutralization of Special Elements used in an SQL CommandThe product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
