DescriptionGitHub Advisory

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.

AnalysisAI

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. The vulnerability exploits the POST /api/ee/serialization/import endpoint by injecting INIT properties into H2 JDBC specifications within crafted serialization archives, triggering arbitrary SQL execution during database synchronization. Authentication as an admin is required (CVSS PR:H), and the vulnerability has been confirmed exploitable on Metabase Cloud infrastructure.

Technical ContextAI

This vulnerability affects Metabase Enterprise Edition's serialization import functionality, specifically the POST /api/ee/serialization/import API endpoint. The root cause is classified as CWE-502 (Deserialization of Untrusted Data), where the application fails to properly validate serialization archives before processing. The attack vector leverages H2 database JDBC connection string manipulation, injecting an INIT property that executes arbitrary SQL commands during the database synchronization process. The affected product per CPE is cpe:2.3:a:metabase:metabase:*:*:*:*:*:*:*:*, encompassing all Enterprise Edition versions containing serialization features introduced in version 1.47. Metabase OSS (Open Source Software) editions are not affected as they lack the vulnerable serialization import codepaths entirely, making this an Enterprise-specific attack surface.

RemediationAI

Upgrade Metabase Enterprise Edition to version 1.54.22, 1.55.22, 1.56.22, 1.57.16, 1.58.10, or 1.59.4 depending on the release branch in use, as documented in the vendor security advisory at https://github.com/metabase/metabase/security/advisories/GHSA-fppj-vcm3-w229. Organizations unable to immediately patch should disable the serialization import endpoint at POST /api/ee/serialization/import to prevent access to vulnerable codepaths, though this workaround may impact legitimate serialization functionality. Additionally, enforce principle of least privilege for admin accounts, implement multi-factor authentication for all administrative access, and monitor API access logs for unexpected serialization import requests.
