The compromised code wasn't actually released. This write-up has a lot of information:
> EDIT Sept 24 — All of my packages on npm have migrated to use environment-scoped staged publishing triggerable only by workflow_dispatch. This means 2FA is always required, so even if (god forbid) an npm or GitHub token is compromised, it will not be possible for the attacker to publish new versions.
So at least that's good to see. It would be nice for them to actually remove the commit from git history, though...
It definitely doesn't inspire confidence in the project taking security seriously.
(Also the "write-up" is almost surely a "Claude-up", though it appears generated by someone external to the project).
