It's been awhile I hope you're doing well!
The vulnerability issue that you reported, if I recall correctly, was relating to server-forwarding attacks via our API playground. We've addressed that issue around 8 months ago, and unfortunately, it was not the root of this incident.
Please correct me if I am wrong though!
For the security of our customers from the publicity we were expecting from the announcement, we've decided to leave out the technical details of the breach in the blog post.
The source of this security incident was due to an uncaught error response in one of our APIs that didn't properly format the response before sending it back to the client. The response contained our internal admin tokens, which can then be used to access internal endpoints, which unveiled sensitive user information.
Our initial patch upon discovering the incident fixed the response of the vulnerable endpoint, but we have since also implemented a sweeping number of security provisions and are also in the process of completely deprecating the admin tokens and GitHub OAuth entirely to prevent an incident like this from ever happening again.
