1Identify exposure identify
grep -r 'wasmtime' . | 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 `wasmtime` を grep し、稼働しているサービス・バージョンを把握する。
-
5Apply temporary workaround mitigate
If your application creates and drops Wasmtime types on multiple threads concurrently, there are no known workarounds.パッチが適用されるまでの応急処置として、If your application creates and drops Wasmtime types on multiple threads concurrently, there are no known workarounds. を実施。回避策の副作用 (機能低下) を確認した上で。
-
6Apply patch patch
Upgrade wasmtime to 25.0.2ステージング環境で 25.0.2 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
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 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。
