Code Injection in dbgate-api (CVE-2026-48017)
Summary
Code injection in dbgate-api (CVE-2026-48017). Successful exploitation can lead to full system takeover. Exploitable via POST /runners/load-reader. Mitigation: upgrade to 7.1.9 or later.
Original description
The description as published by the source.
DbGate is cross-platform database manager. In versions 7.1.8 and prior, the POST /runners/load-reader endpoint in DbGate accepts a functionName parameter that is directly interpolated into a JavaScript code template without any sanitization or validation. An authenticated user (with basic access, no special permissions required) can inject arbitrary JavaScript code that executes on the server with full process privileges, bypassing the require=null sandbox restriction. An authenticated user with basic access (no admin role, no run-shell-script permission required) can: execute arbitrary OS commands on the DbGate server with the privileges of the Node.js process, read/write any file accessible to the process, pivot to connected databases by reading connection credentials from DbGate's storage, and compromise the host system - in Docker deployments, this typically means root access within the container. Version 7.1.9 contains a patch.

CVE-2026-48017 (dbgate-api) — CWE-94 / CVSS v3 8.8
Attack vector: remote (network-reachable) / no user interaction
Attack surface: POST /runners/load-reader / functionName / loadReader / loaderScriptTemplate
Patched: 7.1.9 — apply immediately
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
Arbitrary code execution (CWE-94) exists in dbgate-api. Attackers reach the vulnerable code path via POST /runners/load-reader.
Check the vendor advisory for the affected versions of dbgate-api. Attack surface: POST /runners/load-reader / functionName / loadReader / loaderScriptTemplate.
Severity: High (CVSS 8.8/10). Successful exploitation can lead to full system takeover.
Update to 7.1.9.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual POST /runners/load-reader requests with malformed payloads or SQL meta-characters. Run grep -r 'dbgate-api' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response actions
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'dbgate-api' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
dbgate-apiを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'POST /runners/load-reader' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
POST /runners/load-readerへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Apply patch patch
Upgrade dbgate-api to 7.1.9ステージング環境で 7.1.9 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 2 で見つけた異常検知の続報チェックを含めること。
-
4Post-deployment verification verify
Replay attack against POST /runners/load-reader on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
