I did a quick test and seems like the full admin access that I used to get is slightly fixed/changed. I'm wondering if there was an issue and I have enough data to show there were full compromised of all users data, but it is changed now (might still be vulnerable but let's say it's not). should I still release something? they should have notified their users of such an issue right?
