🔍 Detection
Search webserver/proxy logs for unusual `POST /api/v1/meters` requests with malformed payloads or SQL meta-characters. Run `grep -r 'github.com/openmeterio/openmeter' .` against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response Actions (7 steps)
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'github.com/openmeterio/openmeter' . | 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 `github.com/openmeterio/openmeter` を grep し、稼働しているサービス・バージョンを把握する。
-
3Hunt for indicators of compromise detect
grep 'POST /api/v1/meters' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで `POST /api/v1/meters` 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。
-
6Apply patch patch
Upgrade github.com/openmeterio/openmeter to 1.0.0-beta.228ステージング環境で 1.0.0-beta.228 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 3 で見つけた異常検知の続報チェックを含めること。
-
7Post-deployment verification verify
Replay attack against POST /api/v1/meters 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 3 と同じログクエリでアラート再発が無いか継続監視。
