What is CVE-2026-33121?
CVE-2026-33121 is a high-severity SQL injection vulnerability in Dataease Dataease, published on 16 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
Weakness: CWE-89
