SQL Injection in DataEase Dataset Export Enables Data Extraction

Publication date: 2026-04-16

Last updated on: 2026-04-20

Assigner: GitHub, Inc.

Description
DataEase is an open source data visualization analysis tool. Versions 2.10.20 and below contain a SQL injection vulnerability in the dataset export functionality. The expressionTree parameter in POST /de2api/datasetTree/exportDataset is deserialized into a filtering object and passed to WhereTree2Str.transFilterTrees for SQL translation, where user-controlled values in "like" filter terms are directly concatenated into SQL fragments without sanitization. An attacker can inject arbitrary SQL commands by escaping the string literal in the filter value, enabling blind SQL injection through techniques such as time-based extraction of database information. This issue has been fixed in version 2.10.21.

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

This vulnerability exists in DataEase versions 2.10.20 and below, specifically in the dataset export functionality. It is a SQL injection vulnerability caused by the expressionTree parameter in the POST /de2api/datasetTree/exportDataset endpoint. The parameter is deserialized into a filtering object and passed to a function that translates filters into SQL queries. User-controlled values in "like" filter terms are directly concatenated into SQL fragments without proper sanitization, allowing an attacker to inject arbitrary SQL commands.

This enables blind SQL injection attacks, such as time-based extraction of database information, where an attacker can infer data by observing response times. The issue has been fixed in version 2.10.21.

Compliance Impact

The vulnerability is a SQL injection in DataEase versions 2.10.20 and below, which allows attackers to execute arbitrary SQL commands. This can lead to unauthorized access to sensitive data stored in the database.

Such unauthorized data access can result in violations of data protection regulations and standards like GDPR and HIPAA, which require strict controls to protect personal and sensitive information from unauthorized disclosure or manipulation.

Therefore, if exploited, this vulnerability could compromise compliance with these regulations by exposing or altering protected data.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary SQL commands on the database used by DataEase. This can lead to unauthorized access to sensitive data, data leakage, data modification, or even deletion.

Because it is a blind SQL injection, attackers can extract information from the database without direct visibility, potentially compromising the confidentiality and integrity of the data.

Mitigation Strategies

The vulnerability exists in DataEase versions 2.10.20 and below and has been fixed in version 2.10.21.

The immediate step to mitigate this vulnerability is to upgrade DataEase to version 2.10.21 or later.
