Description

DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a SQL injection vulnerability in the API datasource update process. When a new table definition is added during a datasource update via /de2api/datasource/update, the deTableName field from the user-submitted configuration is passed to DatasourceSyncManage.createEngineTable, where it is substituted into a CREATE TABLE statement template without any sanitization or identifier escaping. An authenticated attacker can inject arbitrary SQL commands by crafting a deTableName that breaks out of identifier quoting, enabling error-based SQL injection that can extract database information. This issue has been fixed in version 2.10.21.
