Juggle <= 1.6.0 - Unauthenticated Exposed H2 Database Console

id: CVE-2026-67208

info:
  name: Juggle <= 1.6.0 - Unauthenticated Exposed H2 Database Console
  author: str4k3r
  severity: critical
  description: |
    Juggle ships the H2 database web console enabled and reachable from
    non-localhost by default. No application-level authentication covers
    the /h2-console path, and the shipped default datasource credentials
    (sa/juggle) are known. An unauthenticated remote attacker can reach the
    console and, using the default credentials, achieve OS command
    execution on the host via the H2 CREATE ALIAS Runtime.exec() technique.
  impact: |
    Unauthenticated remote attackers can execute arbitrary OS commands with root privileges, leading to full system compromise.
  remediation: |
    Update to the latest version and change default credentials; restrict access to /h2-console.
