➡ Base Steps :

1. Create two accounts if possible or else enumerate users first.
2. Check if the endpoint is private or public and does it contains any kind of id param.
3. Try changing the param value to some other user and see if does anything to their account.

➡ Testcase 1: Add IDs to requests that don’t have them

GET /api/MyPictureList → /api/MyPictureList?user_id=<other_user_id>

Pro tip: You can find parameter names to try by deleting or editing other objects and seeing the parameter names used.
