## Overview

DataEase is an open source data visualization and analysis tool. Prior to 2.10.26, authenticated users can store a crafted custom dateFormat for a dataset field. DatasetTableFieldDTO.dateFormat is inserted without validation into date conversion templates used by Dimension2SQLObj, CustomWhere2Str, Field2SQLObj, WhereTree2Str, and ExtWhere2Str. When a chart renders the field on a cross-datasource dataset, Calcite parsing is bypassed and the crafted format can directly alter the generated SQL. On a single-datasource dataset, exploitation additionally requires the payload to survive Calcite reserialization as a valid string literal. Successful exploitation can compromise the confidentiality, integrity, and availability of the backend database. This issue is fixed in version 2.10.26.
