Vulnerability Title
DbGate: Unauthenticated Remote Code Execution via JSON Script Runner
Source: CVE Program / CVE List V5
Vulnerability Description
DbGate is cross-platform database manager. In versions 7.1.8 and prior, DbGate's JSON script runner (`POST /runners/start`) allows remote code execution via code injection in the `functionName` parameter of JSON script `assign` commands. The `functionName` value is interpolated directly into dynamically generated JavaScript source code via string concatenation. The generated code is then executed in a forked Node.js child process. Version 7.1.9 contains a patch.

II. Public POCs for CVE-2026-47668

# POC Description Source Link Shenlong Link
1 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. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-47668.yaml POC Details
