By default, GitHub sends notifications for new Dependabot alerts to all users who have at least write permissions for the affected repository. This default recipient list includes individuals with Write, Maintain, or Admin roles. The system is designed to alert those who can commit code and resolve the identified vulnerabilities. Since the "Write" permission is the minimum level required to receive these alerts, and the higher-level "Maintain" and "Admin" roles inherently include write access, this option is the most accurate and comprehensive answer.

B. Users with Admin privileges to the repository

This is too restrictive. Users with only Write or Maintain permissions also receive default notifications, not just administrators.

C. Users with Maintain privileges to the repository

This is incomplete. Users with Write and Admin permissions are also included in the default notification group.

D. Users with Read permissions to the repository

This is incorrect. Users with read-only access cannot act on vulnerabilities and are not included in the default notification recipients for security alerts.

1. GitHub Docs

"Configuring notifications for Dependabot alerts."

Section: Dependabot alerts notifications

Content: "When a new Dependabot alert is detected

GitHub notifies all users with access to security alerts for the repository according to their notification preferences. ... By default

we notify people with write

maintain

or admin permissions in the affected repositories." This directly confirms that users with Write

Maintain

or Admin permissions are the default recipients.

2. GitHub Docs

"Repository roles for an organization."

Section: Permissions for repository roles

Content: This document outlines the hierarchy of permissions (Read < Triage < Write < Maintain < Admin). It substantiates that "Write" is the foundational permission level among the three roles that receive alerts

and that Maintain and Admin roles are supersets of Write permissions.
