Detailsinfo

A vulnerability classified as critical was found in DataEase up to 2.10.20. Affected by this vulnerability is an unknown code of the file /de2api/datasetTree/exportDataset. The manipulation of the argument expressionTree with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-33082 since 03/17/2026. The exploitation appears to be easy. The attack can be launched remotely.
