We Hacked Apple for 3 Months: Here’s What We Found

This is an incredibly detailed writeup from 3 months of hacking on Apple's services and exposing a number of issues that were remedied.

There were a total of 55 vulnerabilities discovered with 11 critical severity, 29 high severity, 13 medium severity, and 2 low severity reports. These severities were assessed by us for summarization purposes and are dependent on a mix of CVSS and our understanding of the business related impact.

As of October 6th, 2020, the vast majority of these findings have been fixed and credited. They were typically remediated within 1-2 business days (with some being fixed in as little as 4-6 hours).

This is a very interesting read to see the kind of vulnerabilities that are out there and how they can be exploited.
