Authenticated code execution via Unicode JDBC filter bypass
Published Jul 7, 2026 · Updated Jul 7, 2026
Code injection in FIT2CLOUD DataEase before 2.10.24 allows remote attackers to execute arbitrary code through a crafted H2 JDBC URL. JdbcUrlSecurityPolicy lowercases the supplied URL before checking blocked fragments; H2 instead uppercases the URL and treats U+0131 as part of INIT. A valid DataEase token and access to the datasource schema endpoint are required; successful exploitation runs code in the server process context.

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.
