Description
Metabase is an open source business intelligence and embedded analytics tool. In Metabase Enterprise prior to versions 1.54.22, 1.55.22, 1.56.22, 1.57.16, 1.58.10, and 1.59.4, authenticated admins on Metabase Enterprise Edition can achieve Remote Code Execution (RCE) and Arbitrary File Read via the `POST /api/ee/serialization/import` endpoint. A crafted serialization archive injects an `INIT` property into the H2 JDBC spec, which can execute arbitrary SQL during a database sync. We confirmed this was possible on Metabase Cloud. This only affects Metabase Enterprise. Metabase OSS lacks the affected codepaths. All versions of Metabase Enterprise that have serialization, which dates back to at least version 1.47, are affected. Metabase Enterprise versions 1.54.22, 1.55.22, 1.56.22, 1.57.16, 1.58.10, and 1.59.4 patch the issue. As a workaround, disable the serialization import endpoint in their Metabase instance to prevent access to the vulnerable codepaths.
Analysis
Remote Code Execution and Arbitrary File Read in Metabase Enterprise Edition allows authenticated administrators to execute arbitrary code and read sensitive files via malicious serialization archives. Affected versions span at least 1.47 through 1.59.3, with patches released in versions 1.54.22, 1.55.22, 1.56.22, 1.57.16, 1.58.10, and 1.59.4. …

Remediation
Within 24 hours: Identify all Metabase Enterprise instances in your environment and confirm current version numbers; restrict administrative access to the serialization import API endpoint (/api/ee/serialization/import) via network or WAF controls. Within 7 days: Upgrade to patched versions (1.54.22, 1.55.22, 1.56.22, 1.57.16, 1.58.10, or 1.59.4 depending on your current release line); audit admin account activity logs for suspicious import operations. …
