CVE-2026-47668 dbgate vulnerability
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.

dbgate should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.
Who is affected
Affected versions
- < 7.1.9
Fixed versions
- Apply the latest vendor-supported patched version.
How to fix it
CVE-2026-47668 affects dbgate and involves code or command execution. Successful exploitation may let an attacker run unintended code or operating-system commands in the affected process. Treat this as a high-priority fix, especially when the affected component or endpoint is reachable by untrusted users. Upgrade dbgate to 7.1.9 or a later vendor-supported fixed release.
- Inventory every deployment, device, package, plugin, container, build, and environment that uses dbgate.
- Compare the installed version with the recorded affected range: < 7.1.9.
- Upgrade dbgate to 7.1.9 or a later vendor-supported fixed release.
- Until patched, disable the affected feature, limit untrusted input, and run the service with the lowest practical privileges.
- Review configuration, roles, tokens, network paths, and exposed endpoints connected to dbgate; remove access that is not required.
- Review process, shell, web, audit, and network logs for unexpected commands, child processes, downloads, callbacks, or changed files.
- If exploitation is suspected, isolate affected assets, preserve evidence, rotate exposed credentials or keys, restore trusted data, and rebuild compromised systems before returning them to service.

Verify the fix
- Confirm every affected asset now runs the fixed vendor-supported release or has the documented mitigation for CVE-2026-47668 in place.
- Use a safe regression test to confirm the affected code or command execution path no longer produces the vulnerable behavior.
- Confirm temporary access controls, endpoint restrictions, network blocks, and least-privilege settings remain effective after the update.
- Review post-remediation logs and rerun Fixnx plus the relevant package, dependency, firmware, browser, or product-specific security check.
- Document affected assets, versions, changes, validation evidence, reviewed logs, and any credential rotation, cleanup, or replacement completed.
