CVE-2025-62420Public exploitNetwork attack vector

Remote code execution via mismatched H2 JDBC fields

Published Oct 17, 2025 · Updated Oct 17, 2025

JDBC driver bypass in DataEase before 2.10.14 allows remote authenticated users to execute code through a crafted H2 data-source request. The getJdbc function in H2.java validates jdbcUrl as H2 but returns the independently supplied jdbc value and permits a caller-selected JDBC driver to open it. Access to the authenticated datasource validation endpoint is sufficient to load a malicious connection chain and execute commands in the server process.
