SQL Injection in DataEase Prior to 2.10.23

Publication date: 2026-07-15

Last updated on: 2026-07-18

Assigner: GitHub, Inc.

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 ID Description
CWE-89 The 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.

Executive Summary

CVE-2026-50030 is a SQL injection vulnerability in DataEase, an open-source data visualization tool. It allows attackers to execute arbitrary SQL queries on connected databases through the SQL preview feature. The issue exists in versions prior to 2.10.23 and enables direct data disclosure by exploiting improperly secured API endpoints.

Detection Guidance

Check for unauthorized access to the /de2api/datasetData/previewSql endpoint by monitoring HTTP requests containing SQL queries or Base64-encoded payloads. Inspect logs for suspicious queries like SELECT statements targeting core_menu or other sensitive tables.

Impact Analysis

An attacker could extract sensitive data from databases connected to DataEase by sending crafted requests to the vulnerable endpoint. This could lead to unauthorized access to tables, records, or other confidential information stored in the datasource.

Compliance Impact

This vulnerability could violate compliance requirements like GDPR (data protection) and HIPAA (health data privacy) by enabling unauthorized data access. It risks exposing sensitive personal or health information, leading to legal penalties, reputational damage, and loss of trust. Organizations using vulnerable versions must upgrade to mitigate compliance risks.

Mitigation Strategies

Upgrade DataEase to version 2.10.23 or later immediately. If upgrading is not possible, restrict access to the /de2api/datasetData/previewSql endpoint and ensure proper permission checks are enforced on all preview methods.
