Response actions
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'github.com/seaweedfs/seaweedfs' . | 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/seaweedfs/seaweedfsを grep し、稼働しているサービス・バージョンを把握する。 -
2Apply temporary workaround mitigate
Restrict volume server gRPC ports to trusted hosts via firewall / network policy, and enable mTLS via `security.toml`.パッチが適用されるまでの応急処置として、Restrict volume server gRPC ports to trusted hosts via firewall / network policy, and enable mTLS via
security.toml. を実施。回避策の副作用 (機能低下) を確認した上で。 -
3Apply patch patch
Upgrade github.com/seaweedfs/seaweedfs to 0.0.0-20260512171120-69da20bdaec9ステージング環境で 0.0.0-20260512171120-69da20bdaec9 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を含めること。
-
4Post-deployment verification verify
Confirm patched version is live in production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。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
