pick your poison:

- you are vulnerable for 7 days because of a now public update

- you are vulnerable for x (hours/days) because of a supply chain attack

I think the answer is rather simple: subscribe to a vulnerability feed, evaluate & update. The amount of times automatic updates are necessary is near zero as someone who has ran libraries that are at times 5 to 6 years out of date exposed to the internet without a single event of compromise and it's not like these were random services, they were viewed by hundreds of thousands of unique addresses. There was only 3 times in the last 4 years where I had to perform updates due to a publically exposed service where these vulnerabilities affected me.

Okay, the never being compromised part is a lie because of php, it's always PHP (monero-miner I am sure everyone is familiar with). The solution for that was to stop using PHP and assosiated software.

Another one I had problems with was CveLab (GitLab if you couldn't tell), there has been so many critical updates pointing to highly exploitable CVE's that I had decided to simply migrate off it.

In conclusion avoiding bad software is just as important as updates from my experience lowering the need for quick and automated actions.
