Somehow they let attackers send themselves password reset links to arbitrary Gitlab accounts, apparently. Not good.

A change was made in 16.1.0 to allow users to reset their password through a secondary email address. The vulnerability is a result of a bug in the email verification process. The bug has been fixed with this patch, and as mentioned above, we have implemented a number of preventive security measures to protect customers.
Struggling to figure out what the heck they did. Some kind of injection attack to send the email to an arbitrary account? How would you even mess that up in the first place
If I had to guess I'd say the email address was sent as part of the request and not verified.
A patch from January and MFA prevents account takeover.
If you're not updating gitlab for over three months, across max severity security patches, you're negligent.
I had a friend whose instance was hacked only a few hours after the issue was disclosed. Bots had swarmed the internet in just a day
