 ### Scenario #1
 
-The User model implements a toJSON() method to serialize a user object as JSON.
-While implementing the `GET /v1/articles/{article_id}/comments/{comment_id}`
-endpoint that returns details about a specific comment in an article and basic
-details about its author, the developer finds the toJSON() method and decides to
-use it (without thinking about the sensitive details it may expose). The mobile
-team is using the endpoint in the articles view, rendering only relevant data.
-An attacker sniffs the mobile app traffic and finds about the sensitive data
