CVE-2026-47670: Authenticated Remote Code Execution via loadReader functionName code injection in DbGate
DbGate is cross-platform database manager.
CVSS 9.4 Critical EPSS 1.8% · p78
Should you act?
Critical, preconditions apply
Severe if exploited, but exploitation needs conditions that may not apply to you. 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 1.8%, percentile 78: FIRST’s model estimates a 1.8% chance of exploitation activity in the next 30 days, higher than 78% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
dbgate-api(npm) <= 7.1.8, fixed in 7.1.9. Check your lockfile, including transitive dependencies.
What it is
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.
From the GitHub advisory
Summary
DbGate is 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().
Details
Code injection via functionName in loadReader
The /runners/load-reader endpoint interpolates the functionName parameter directly into a dynamically generated JavaScript script template without any sanitization:
Weakness type: CWE-77, CWE-78.

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 no, technical impact total.
- FIRST EPSS (model of 2026-10-21): 1.76% probability of exploitation activity in the next 30 days; percentile 78.
