Original description

The description as published by the source.

The /debug/pprof/cmdline endpoint in Dgraph Alpha discloses the command-line arguments used to start the process, which may include the administrator's authentication token if provided via the --auth_token flag. This allows an unauthenticated remote attacker to obtain the token and gain full administrative access to the Dgraph cluster.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

1
Identify exposure identify
```
grep -r 'github.com/dgraph-io/dgraph' . | 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/dgraph-io/dgraph を grep し、稼働しているサービス・バージョンを把握する。
2
Apply patch patch
```
Upgrade github.com/dgraph-io/dgraph to 25.3.2
```
ステージング環境で 25.3.2 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を含めること。
3
Post-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。
