What is CVE-2026-53751?

DataEase, an open-source data visualization and analysis tool, has revealed a security flaw in its handling of H2 database JDBC URL validation. Prior to version 2.10.24, this vulnerability allows attackers to bypass validation checks using specific Unicode characters. The difference in case-conversion behavior between DataEase and H2 parsing can facilitate the injection of malicious parameters into JDBC connection strings, leading to potential arbitrary code execution. Users are urged to update to version 2.10.24 or later to mitigate this risk.
