What is CVE-2026-40900?

The DataEase platform has a SQL injection flaw in the /de2api/datasetData/previewSql endpoint. This vulnerability allows attackers to execute unauthorized SQL statements due to insufficient validation of user-supplied input. When combined with a JDBC blocklist bypass that permits multiple queries, an attacker can escape the controlled subquery context and run arbitrary SQL commands, including potentially harmful write operations, provided they possess valid datasource credentials. This access enables full read and write capabilities against the underlying database. The issue has been resolved in version 2.10.21, making it critical for users to update their installations.

Affected Version(s)
