CVE-2026-47668: DbGate: Unauthenticated Remote Code Execution via JSON Script Runner
DbGate is cross-platform database manager.
CVSS 10.0 Critical EPSS 3.9% · p90
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 3.9%, percentile 90: FIRST’s model estimates a 3.9% chance of exploitation activity in the next 30 days, higher than 90% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
dbgate-serve(npm) <= 7.1.8, fixed in 7.1.9. Check your lockfile, including transitive dependencies.
What it is
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.
From the GitHub advisory
Summary 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.
Details Step 1: User Input Entry Point
File: packages/api/src/controllers/runners.js - start() method
The /runners/start endpoint accepts a POST body containing a script object. When script.type == 'json', the request follows a different code path than raw shell scripts:
This path skips: 1. The run-shell-script permission check 2. The allowShellScripting platform-level check
Weakness type: CWE-20, CWE-94, CWE-1188.

CVSS measures how bad a flaw is if exploited, not how likely exploitation is. Read it next to the exploitation data below.
Exploitation and urgency
- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc, automatable yes, technical impact total.
- FIRST EPSS (model of 2026-10-21): 3.88% probability of exploitation activity in the next 30 days; percentile 90.
