Yea, all the new advice around using dependency cooldowns only works if _someone_ is installing these things before you and finding the vulnerabilities.
It seems like the advice right now is to become a freerider while there are still people installing closer to release that will do free work for you finding out there's something nasty in the release.
Once everyone is waiting 2 weeks to install an update, then the value of everyone waiting goes down dramatically.
This is how a chunk of people function anyway. There are plenty of people that choose to not install "point zero" release for software of a certain importance, assuming with any major changes there are often bugs that come along with it.
In this case, since the number of cool down days is configurable, even if everyone was using it we would still likely see a somewhat smooth curve for adoption, since not everyone will choose the same delay and the delay time will likely map closely to how people want to habdke risk.
It's all a trade off, just like it's always been. This just makes it simpler to act on what you want your risk/comfort level to be.
not really, there are a number of security companies doing analysis of any new packages looking for supply chain attacks, so if you wait a couple of days, till their analysis is complete, you're reducing the risk of hitting a compromised package.
you have 1.0 installed. you enable 7 day cooldowns. an exploit is discovered in 1.0, and 1.1 is immediately released to fix the exploit. do you sit on 1.0 for 7 days?
> A version whose source does not expose created_at, such as older gem servers, historical entries from before the v2 cutover, or private registries still on the v1 format, is treated as outside the window and stays resolvable.
How is that not an easy exploit to circumvent the cooldown?
Most gems in Ruby/Rails projects come from rubygems, so if they were published long ago, any exploits should have already been found hopefully. Any old gems that would attempt to release a new compromised version would now get a created_at timestamp and the cooldown applies.
Unless you can compromise the gem server to overwrite created_at fields, I don't see any exploits here.
Private gem servers are either already trusted (if they're your own) or already under some scrutiny and extra care already being taken (ideally), but this last case applies to very few projects I'm sure.
Every security company and their cousin wants to be the one to find the next big dependency malware.

If not, and the current defacto standard gem server doesn't accept v1 anymore, we're good I suppose?
