CVE-2026-59826Network attack vector

Administrator code execution via unchecked H2 INIT property

Published Jul 9, 2026 · Updated Jul 9, 2026

Code injection in Metabase allows remote authenticated users with administrator access to execute arbitrary Java code on the application server. The enterprise destination-database creation endpoint persisted crafted H2 details without applying the existing INIT-property rejection before connection testing. Network access and an administrator account are required; successful exploitation compromises the Metabase server process.
