SCA: security update for ai.h2o:h2o-core (GHSA-qmcv-hh7c-3m56)

critical Tenable Self-Hosted Container Security Plugin ID 441133

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-3960)

Solution

Update the ai.h2o:h2o-core library and its related packages to version 3.46.0.10 or later.
