```
`github` alert.id=* action=create 
| rename repository.full_name as repository, repository.html_url as repository_url sender.login as user 
| stats min(_time) as firstTime max(_time) as lastTime by action alert.affected_package_name alert.affected_range alert.created_at alert.external_identifier alert.external_reference alert.fixed_in alert.severity repository repository_url user 
| eval phase="code" 
| `security_content_ctime(firstTime)` 
| `security_content_ctime(lastTime)` 
| `github_dependabot_alert_filter`
```

#### Macros
The SPL above uses the following Macros:
* [security_content_ctime](https://github.com/splunk/security_content/blob/develop/macros/security_content_ctime.yml)
* [github](https://github.com/splunk/security_content/blob/develop/macros/github.yml)

Note that `github_dependabot_alert_filter` is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

* repository.full_name
* repository.html_url
* action
* alert.affected_package_name
