dbgate: Improper Neutralization of Special Elements used in a Command
CVE-2026-47670 is a critical-severity improper neutralization of special elements used in a command vulnerability in dbgate, with a CVSS 4.0 base score of 9.4 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected dbgate versions: < 7.1.9. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.76% chance of exploitation within 30 days, higher than 78% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of dbgate you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.

Official description
DbGate is cross-platform database manager. Versions 7.1.8 and prior are vulnerable to authenticated Remote Code Execution (RCE). Any user with valid DbGate credentials can execute arbitrary OS commands as root by exploiting an unsanitized `functionName` parameter in the `/runners/load-reader` endpoint. The `require = null` mitigation is trivially bypassed via dynamic `import()`. Version 7.1.9 contains a patch.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
