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.

Security readout for executives and security teams

Plain-English summary

A vulnerable Metabase server can be made to run arbitrary Java code if an authenticated administrator adds a specially crafted H2 database connection. This is critical because successful abuse affects the Metabase server itself, not just dashboard data. Fixed versions are available.

Executive priority

Treat this as urgent for any production Metabase instance. Although exploitation requires admin privileges, a successful attack can compromise the underlying server, so vulnerable systems should be upgraded promptly and admin access reviewed.

Technical view

Metabase versions 1.55.0 through the listed vulnerable branch ranges failed to validate unsafe H2 connection properties on one database-creation path. The flaw is CWE-94 code injection with CVSS 9.1, requiring high privileges but allowing network-reachable arbitrary Java code execution with changed scope.

Likely exposure

Exposure is limited to Metabase deployments running affected versions where an authenticated administrator can create database connections. Internet-facing admin panels or compromised admin accounts raise urgency.

Exploitation context

The provided sources do not show active exploitation, and KEV is false. The attack requires administrator privileges, but the impact is severe because it can execute code on the Metabase server.

Researcher notes

The key research boundary is the vulnerable database-creation path and H2 connection property validation. Sources identify fixed versions and a remediation commit, but do not provide evidence of exploitation in the wild.

Mitigation direction

  • Upgrade to 1.58.15.1, 1.59.12, 1.60.6.3, 1.61.2, or later fixed versions.
  • Prioritize externally reachable or shared Metabase instances first.
  • Restrict Metabase administrator access to trusted users only.
  • Review vendor advisory and release notes for branch-specific upgrade guidance.
  • Monitor for unexpected Metabase database connection changes.

Validation and detection

  • Inventory all Metabase instances and record exact versions.
  • Compare versions against the affected branch ranges in the CVE record.
  • Confirm upgraded instances report a fixed version.
  • Review configured database connections for unexpected H2 entries.
  • Check administrative change history where available for unusual database creation events.
