The Bitwarden security team identified and contained a malicious package that was briefly distributed through the npm delivery path for @bitwarden/
[email protected] between 5:57 PM and 7:30 PM (ET) on April 22, 2026, in connection with a broader Checkmarx supply chain incident. The investigation found no evidence that end user vault data was accessed or at risk, or that production data or production systems were compromised. Once the issue was detected, compromised access was revoked, the malicious ...
As someone completely unfamiliar with the JavaScript mess, are these security issues specific to npm the actual repository or npm the package manager?
If it’s the latter, does using something else like yarn or bun instead help?
It’s not, it’s a problem of every package manager that do not use sources and checksums, like rust and python. Take a look at this article that does a better job then me at explaining the situation.
Given that he lied about the results of the analysis he is using to prove his point, I find it hard to trust anything in this article.
In the analysis, Harvey said only 8 repositories did not match their upstream repos. The other problems were issues like not including the VCS info, squashing history, etc.
EDIT: Also, I just noticed that he called it a “recent” analysis. It’s roughly a two year old analysis. I expect things have improved a bit since then, especially since part of the problem was packaging using older versions of Cargo.

Competent standard lib + decentralized libs + checksum db.
While the article is a bit theatralic, it offers important arguments.
There are some good points in it, though I wouldn’t really consider go dependencies all that decentralized in practice and I don’t understand how checksum db will protect against supply chain attacks with stolen credentials, but I admit I haven’t looked into the details.
I think npm allows installation scripts which do make this worse, as a package can run arbitrary command at install time.
Npm has gotten a few config options that prevent this behaviour. We can only hope that they will become the default eventually.
