## Technical details

An SQL injection vulnerability exists in DataEase prior to version 2.10.23 due to improper neutralization of user-provided SQL in the preview functionality. The endpoint `/de2api/datasetData/previewSql` accepts a `PreviewSqlDTO` object containing Base64-encoded SQL. The backend decodes this input and passes it to `CalciteProvider.fetchResultField`, which executes the query via `prepareStatement(...).executeQuery()` without sufficient validation. Furthermore, the permission check in `CorePermissionManage.checkAuth` was found to return 'true' unconditionally in affected versions, allowing attackers to query any reachable datasource table and receive the results in the API response.
