CVE-2025-66913Public exploitNetwork attack vector

Unauthenticated code execution via H2 JDBC directives

Published Jan 8, 2026 · Updated Jan 8, 2026

Code injection in JimuReport 2.1.3 and earlier allows remote attackers to execute arbitrary Java code through crafted H2 JDBC URLs. The /jmreport/testConnection endpoint passes the dbUrl value directly to the H2 driver, which interprets INIT or CREATE ALIAS directives as Java code. No authentication or user interaction is required; successful exploitation runs code with the JimuReport server process's privileges.
