CVE-2026-50030 dataease CVE debrief

CVE-2026-50030 is a high-severity SQL injection vulnerability in DataEase, a data visualization and analysis tool. The vulnerability allows attackers to query arbitrary readable datasource tables and return them in preview responses. This issue was fixed in version 2.10.23. Affected users should apply the patch to prevent exploitation. The vulnerability exists in the DataEase SQL preview feature, which exposes the DatasetDataApi.previewSql/previewSqlCheck through /de2api/datasetData/previewSql. The endpoint accepts PreviewSqlDTO.sql, PreviewSqlDTO.datasourceId, and PreviewSqlDTO.isCross, then stores decoded SQL in datasourceRequest.query. The CalciteProvider.fetchResultField executes it with prepareStatement(...).executeQuery(), allowing arbitrary readable datasource tables to be queried and returned in preview responses. Users of DataEase versions prior to 2.10.23 should verify their deployments and apply patches or mitigations as needed. This includes operators, administrators, and security teams responsible for managing DataEase deployments.
