    H2O-3 is Vulnerable to Code Injection

    CVE-2026-3960 · GHSA-qmcv-hh7c-3m56

    Affected
    • Maven ai.h2o:h2o-core < 3.46.0.10
    Fixed in
    3.46.0.10· Vendor fix available
    Issue
    A critical remote code execution vulnerability exists in the unauthenticated REST API endpoint /99/ImportSQLTable in H2O-3 version 3.46.0.9 and prior. The vulnerability arises due to insufficient security controls in the parameter blacklist mechanism, which only targets MySQL JDBC driver-specific dangerous parameters. An attacker can bypass these controls by switching the JDBC URL protocol to jdbc:postgresql: and exploiting PostgreSQL JDBC driver-specific parameters such as socketFactory and socketFactoryArg. This allows unauthenticated attackers to execute arbitrary code on the H2O-3 server with the privileges of the H2O-3 process. The issue is resolved in version 3.46.0.10.

    Recommended action: Upgrade to 3.46.0.10 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.

    H2O Deserialization of Untrusted Data Vulnerability

    CVE-2024-10553 · GHSA-h7xg-cmpp-48hf

    Affected
    • Maven ai.h2o:h2o-core < 3.46.0.6
    Fixed in
    3.46.0.6· Vendor fix available
    Issue
    A vulnerability in the h2oai/h2o-3 REST API versions 3.46.0.4 allows unauthenticated remote attackers to execute arbitrary code via deserialization of untrusted data. The vulnerability exists in the endpoints POST /99/ImportSQLTable and POST /3/SaveToHiveTable, where user-controlled JDBC URLs are passed to DriverManager.getConnection, leading to deserialization if a MySQL or PostgreSQL driver is available in the classpath. This issue is fixed in version 3.46.0.6.

    Recommended action: Upgrade to 3.46.0.6 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
