GitHub GraphQL APIでVulnerability Alertを取得する
こんにちは、CX事業本部 IoT事業部の若槻です。
Dependabot alertのalert一覧を取得したく方法を調べていたところ、REST APIやCLIにはAPIが無く、GraphQL APIにのみAPIが用意されていました。
今回は、GitHub GraphQL APIでのVulnerability Alert(Dependabot alert)の取得を試してみました。
基本的な使い方(curl)
GitHub GraphQL APIの基本的な使い方はこちらに書いてあります。
curlで試してみます。Personal access tokensが必要なのでこちらで発行しておきます。
$ GH_API_TOKEN=<GH_API_TOKEN> $ query="\"query { viewer { login }}\"" $ curl \ -H "Authorization: bearer $GH_API_TOKEN" \ -X POST -d "{ \"query\": ${query}}" \ https://api.github.com/graphql {"data":{"viewer":{"login":"cm-rwakatsuki"}}}
クエリ結果が取得できていますね。
Vulnerability Alertの取得(Explorer)
GitHubが用意しているExplorerでGraphQL APIを試すこともできます。
こちらを参考にExplorerでVulnerability Alertの一覧を取得してみます。
取得対象のRepositoryでは、Open中のalert1件とClose済みのalert1件が記録されています。
次のようにクエリを実行します。
query($repo_name:String!, $owner:String!) { repository(name: $repo_name, owner: $owner) { vulnerabilityAlerts(first: 100) { nodes { createdAt dismissedAt state securityVulnerability { package { name } advisory { description } } } } } } { "owner": "cm-rwakatsuki", "repo_name": "aws-cdk-v2-project" }
すべてのalertが取得できました。
{ "data": { "repository": { "vulnerabilityAlerts": { "nodes": [ { "createdAt": "2022-04-28T14:12:40Z", "dismissedAt": "2022-05-02T14:26:44Z", "state": "DISMISSED", "securityVulnerability": { "package": { "name": "log4js" }, "advisory": { "description": "### Impact\r\nDefault file permissions for log files created by the file, fileSync and dateFile appenders are world-readable (in unix).

次にOPEN
StateのAlertのみフィルターして取得してみます。クエリ内でstate
パラメータを指定します。
query($repo_name:String!, $owner:String!) { repository(name: $repo_name, owner: $owner) { vulnerabilityAlerts(first: 100, states: [OPEN]) { nodes { createdAt dismissedAt state securityVulnerability { package { name } advisory { description } } } } } } { "owner": "cm-rwakatsuki", "repo_name": "aws-cdk-v2-project" }
open中のalertのみ取得できていますね!
{ "data": { "repository": { "vulnerabilityAlerts": { "nodes": [ { "createdAt": "2022-04-30T14:14:00Z", "dismissedAt": "2022-04-30T14:21:10Z", "state": "OPEN", "securityVulnerability": { "package": { "name": "moment" }, "advisory": { "description": "### Impact\nThis vulnerability impacts npm (server) users of moment.js, especially if user provided locale string, eg `fr` is directly used to switch moment locale.\n\n### Patches\nThis problem is patched in 2.29.2, and the patch can be applied to all affected versions (from 1.0.1 up until 2.29.1, inclusive).\n\n### Workarounds\nSanitize user-provided locale name before passing it to moment.js.\n\n### References\n_Are there any links users can visit to find out more?_\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [moment repo](https://github.com/moment/moment)\n" } } } ] } } } }
ただ単に「Open中のalertが1件以上あるか」確認したいなら次のように実行します。id
プロパティを最低限指定する必要があります。
query($repo_name:String!, $owner:String!) { repository(name: $repo_name, owner: $owner) { vulnerabilityAlerts(first: 1, states: [OPEN]) { nodes { id } } } } { "owner": "cm-rwakatsuki", "repo_name": "aws-cdk-v2-project" }
Open中のalertの最初の1件が取得できており、Open中のalertが1件以上あることが分かります。また取得結果がすっきりしています。
{ "data": { "repository": { "vulnerabilityAlerts": { "nodes": [ { "id": "RVA_kwDOHJiaXM6K9Q7q" } ] } } } }
Open中のalertが0件の場合は次のようになります。
{ "data": { "repository": { "vulnerabilityAlerts": { "nodes": [] } } } }
おわりに
GitHub GraphQL APIでのVulnerability Alert(Dependabot alert)の取得を試してみました。
今回方法が分かったので、「Open中のVulnerability Alertが1件以上あればWorkflow実行をFailさせる」なんていう処理をCI/CD上で作ることもできそうです。
