Shai-Hulud malware attack: Tinycolor and over 40 NPM packages compromised

Is there any way to install CLI tools from npmjs without being affected by a recent compromise?

Rust has `cargo install --locked`, which will use the pinned versions of dependencies from the lockfile, and these lockfiles are published for bin packages to crates.io.

But it seems npmjs doesn't allow publishing lockfiles, neither for libraries nor for CLI tools, so if you try to install let's say @google/gemini-cli, it will just pull the latest dependencies that fit the constraints in package.json. Is that true? Is it really this bad? If you try to install a CLI tool on a bad day when half of npmjs is compromised, you're out of luck?

How is that acceptable at all?

Lock files wouldn't work if they were locking transitive dependencies; otherwise the version solver would not have any work to actually do and you'd have many, many versions of the same package rather than a few versions that satisfy all of the version range constraints.

Lots of good ideas since last week, the one I like most being that published packages, especially those that are high in download count, don't actually go publish for a while until after publishing, allowing security scanners to do their thing.

In the Rust ecosystem, you only publish lock files for binary crates. So yeah then you get churn like https://github.com/cargo-bins/cargo-binstall/releases/tag/v1... bumping transitive deps, but this churn/noise doesn't exist for library crates - because the lock file isn't published for them.

npm will use your lockfile if it’s present, otherwise yeah it’s pretty much whatever is tagged and latest at the time (and the version doesn’t even have to change). If npm respected every upstream lockfile, then it could never share a single version that satisfied all dependencies. The bigger issue here is that npm has such unrestricted and unsupervised access to the entire environment at all.

I'm asking in the context of installing a single CLI tool into ~/bin or something. There's no requirement to satisfy all dependencies, because the only dependency I care about is that one CLI tool. All I want is an equivalent of what `cargo install --locked` does — use the top-level lockfile of the CLI tool itself.

That sounds pretty reasonable: npm should allow bundling the lockfile with things that are marked with the type of "project", and whether it actually uses them depending on whether other locked constraints are overriding it. So instead of one lockfile, a prioritized list of them. The UX of dealing with that list could be a sticky wicket though, and npm isn't known for making this stuff easy to begin with.

lib crates have been checking in their Cargo.lock for a while now.

https://github.com/rust-lang/cargo/pull/12382

That Cargo.lock will only be used for the library's own CI though (and also for development if you git clone it). It will not be used by downstream dependencies at all.

npm itself does not know that what you are installing is a CLI tool.

Good CLI tools are bundled before release so they are zero-dependency as far as npm is concerned, which is ideal imho for all CLI tools, but many don't do that.

Looking for "type": "project" is about as close as npm gets to knowing whether something is a command, but lots of libraries do ship with utility commands. npx knows, since it's used for nothing but commands. I've never seen bundling used for anything I've installed through npm; that's more likely for standalone downloads and possibly things like homebrew.

I'll repeat that the bigger problem is that npm has such unfettered access to everything in the user account to begin with. FSM knows it's not strictly an npm problem, it's a Unix problem that's been there since the beginning, just that now, enough of the chickens are coming home to roost that people are starting to notice.
