I mean programming language package managers are just begging to be used as an attack vector. This is why package management should be an OS responsibility across the board and only trusted package sources and publishers should ever be allowed.
Does anyone know how JSR and Deno would do in this type of attack?
Why can’t we have nice things instead.
Tale as old as time.
I don’t know much about NPM (having avoided JS as much as possible for my entire life), but golang seems to have a good solution: ‘vendoring’. One can choose to lock all external dependencies to local snapshots brought into a project, with no automatic updating, but with the option to manually update them when desired.
NPM has that as well. In fact most languages and build tools support that. It’s actually rare to not have support for that these days.
Yes. I can’t imagine being foolish enough to automatically update your external dependencies when you don’t need to.
Ah, good. I wonder why it isn’t used more often – this wouldn’t be such a huge problem then I would hope. (Let me guess – ‘convenience’, the archenemy of security.)
As LiPoly said, it doesn’t really solve the problem. It’s not useless, it does accomplish something, but not that. Locking dependencies isn’t a security thing, it’s a reproducible builds thing. You can accomplish that by just using a traditional static version of everything, but now you’ve got a maintenance headache as you’re constantly needing to go in and update your dependency versions. You could instead use version ranging, but now you never actually know which version of a dependency any given build is going to end up using. Locking allows you to have the best of both worlds.
To understand how this works, lets take a look at a hypothetical. Lets say you have a code base, and a CICD setup. Additionally you’re using a git-flow style release management where your release version is in master, your active development is in develop, and your feature work is done in feature branches. What you do is setup your version ranges to cover what the semantic versions of things say should be compatible (generally locked major version, and possibly locked minor depending on the library, but unlocked patch). In your CICD for CI builds of develop and feature branches you include a step that updates your lock file to the latest version of a library matching your version range. This insures that your develop and feature branches are always using the latest version of dependencies. For your master branch though, its CI job only builds, it never updates the lock file. This means when you merge a release to master your dependencies are effectively frozen. Every build from the master branch is guaranteed to use exactly the same versions of dependencies as when you merged it.
I’m with you but I have regrettably been sucked into the node-i-verse against my will.
This should kill off NPM
You’d be surprised to see how many common libraries have vulnerabilities every week.
Why stop there lets just kill js in its entirity.
