It is unfortunate, but this is evidence (IMO) that Trusted Publishing is still ~~not secure~~ not enough by itself to securely publish from CI, as an attacker inside your CI pipeline or with stolen repo admin creds can easily publish. This isnt new information, TP is not meant to guarantee against this, but migrating to TP away from local publish w/ 2fa introduces this class of attack via compomise of CI. (edit: changed "still not secure" to "still not enough by itself" bc that is the point I want to make) Going to Trusted Publishing / pipeline publishing removes the second factor that typically gates npm publish when working locally. The story here, while it is evolving, seems to be that the attacker compromised the CI/CD pipeline, and because there is no second factor on the npm publish, they were able to steal the OIDC token and complete a publish. Interesting, but unrelated I suppose, is that the publish job failed. So the payload that was in the malicious commit must have had a script that was able to publish itself w/ the OIDC token from the workflow. What I want is CI publishing to still have a second factor outside of Github, while still relying on the long lived token-less Trusted Publisher model. AKA, what I want is staged publishing, so someone must go and use 2fa to promote an artifact to published on the npm side. Otherwise, if a publish can happen only within the Github trust model, anyone who pwns either a repo admin token or gets malicious code into your pipeline can trivially complete a publish. With a true second factor outside the Github context, they can still do a lot of damage to your repo or plant malicious code, but at least they would not be able to publish without getting your second factor for the registry. |
