Very much so. But the vulnerabilities do not tend to be discovered (by developers) until an attack happens. And auto updates are generally how the spread of attacks are limited.
Open source can help slightly. Due to both good and bad actors unrelated to development seeing the code. So it is more common for alerts to hit before attacks. But far from a fix all.
But generally, time between discovery and fix is a worry for big corps. So why auto updates have been accepted with less manual intervention than was common in the past.
