CVE-2026-33121 Details
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 saving process. The deTableName field from the Base64-encoded datasource configuration is used to construct a DDL statement via simple string replacement without any sanitization or escaping of the table name. 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 such as the MySQL version. This issue has been fixed in version 2.10.21.
A SQL injection vulnerability has been identified in DataEase versions prior to 2.10.21. This issue arises in the API datasource saving process, where the deTableName field from the Base64-encoded datasource configuration is used to create a DDL statement. The vulnerability exists because the table name is inserted through simple string replacement without any sanitization or escaping. An authenticated attacker can exploit this by crafting a deTableName that escapes identifier quoting, leading to error-based SQL injection that can extract database information, such as the MySQL version.
Users are advised to upgrade to DataEase version 2.10.21, where this vulnerability has been fixed.
