Remote code execution via locale-dependent JDBC validation
Published Mar 20, 2026 · Updated Mar 20, 2026
Remote code execution in DataEase before 2.10.20 allows remote authenticated users to execute code via a crafted H2 JDBC URL. The datasource validation interface applies String.toUpperCase() with the JVM default locale, while H2 parses the same URL with Locale.ENGLISH, letting iNIT evade the INIT blacklist. Exploitation requires datasource-validation access and a Turkish-locale JVM; H2 then accepts INIT and runs an attacker-supplied script on the server.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
