CVE-2026-59826
CVE-2026-59826 — Metabase: Arbitrary Code Execution via Database Connection Detail Bypass
Metabase is an open-source business intelligence and embedded analytics tool. From 1.55.0 until 1.58.15.1, 1.59.12, 1.60.6.3, and 1.61.2, Metabase did not validate unsafe H2 connection properties on one database-creation code path, allowing an authenticated administrator to register a crafted H2 database connection and execute arbitrary Java code on the Metabase server. This issue is fixed in versions 1.58.15.1, 1.59.12, 1.60.6.3, and 1.61.2.
