> Cache scope is per-repo, shared across pull_request_target runs (which use the base repo's cache scope) and pushes to main. A PR running in the base repo's cache scope can poison entries that production workflows on main will later restore.
This is very difficult to understand, and teach to new people, because everything is configured as YAML, yet everything is layed out in the background to directories and files.
What if your CI pipeline was old-school bash script instead? This would be far more obvious to greater amount of people how it works, and what is left behind by other runs. We know how directories and files work in bash scripts.
Could we go back to basics and manage pipelines as scripts and maybe even run small server?
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.
It has been pulled from the npm registry now.
Crazy that an "orphan" commit pushed to a FORK(!) could trigger this (in npm clients). IMO GitHub deserves much of the blame here. A malicious fork's commits are reachable via GitHub's shared object storage at a URI indistinguishable from the legit repo. That is absolutely bonkers.
We (TanStack) just released our postmortem about this.
Per https://docs.npmjs.com/policies/unpublish:
> If your package does not meet the unpublish policy criteria, we recommend deprecating the package. This allows the package to be downloaded but publishes a clear warning message (that you get to write) every time the package is downloaded, and on the package's npmjs.com page. Users will know that you do not recommend they use the package, but if they are depending on it their builds will not break. We consider this a good compromise between reliability and author control.
I don't even know what to say here, npm.
Imo I think this shouldn't have been possible, as in release should use its own cache and rebuild the rest fresh. It's one thing that the main <> fork boundary was breached, but imo the release process should have run fresh without any caches. Of course hindsight is 20/20.
Given the recent lpe vulns docker 100% won’t cut it.
And containers were never meant primarily as a security boundary anyways
Is there evidence that any downstream packages that may have pulled/included tanstack packages should be considered safe?
Well, one of simplest mitigation is that `pull_request_target` jobs shouldn't have access to write to cache, they can read for performance, but not write.
To extrapolate rule, the `pull_request_target` shouldn't have any ways to invoke external side effects.
In most strict scenario, they shouldn't have access to network at all ... or only to GET <safeUrl> - where safeUrls are somehow vetted previously on main, derived from yarn.locks and similar manifests. Pita to setup, no wonder nobody does that.
Okay it's a security issue, but just mitigate it as we won't fix it.
In a recent comment people asked me how come GitHub Action isn't a positive added feature since MS acquisition.
PSA: npm/bun/pnpm/uv now all support setting a minimum release age for packages. I also have `ignore-scripts=true` in my ~/.npmrc. Based on the analysis, that alone would have mitigated the vulnerability. bun and pnpm do not execute lifecycle scripts by default. Here's how to set global configs to set min release age to 7 days: ~/.config/uv/uv.toml exclude-newer = "7 days"
~/.npmrc
min-release-age=7 # days
ignore-scripts=true
~/Library/Preferences/pnpm/rc
minimum-release-age=10080 # minutes
~/.bunfig.toml
[install]
minimumReleaseAge = 604800 # seconds
npm install <package> --min-release-age 0
pnpm add <package> --minimum-release-age 0
uv add <package> --exclude-newer "0 days"
bun add <package> --minimum-release-age 0
Interesting days.
Maybe a private project, that can't share any cache from the main project where public development is done.
Also only the publish step itself should have access to the publish tokens, and shouldn't run any of the code from the repo. Just publish the previously built tarball, and do nothing more. This would still allow compromising the package somehow in the build step, but at least stealing tokens should become impossible.
pnpm config set minimum-release-age 10080 # 7 days in minutes

Jesus, that's vindictive.
The worm is spreading...
2. NPM still not only publishes them, but also keeps distributing them for anything beyond 5 minutes.
Microsoft/GitHub/NPM can only keep repeating "security is our top priority" so many times. But NPM still doesn't detect these simple attacks, and we keep having this every week.
Another worry that I've had recently is that anybody who is able to get Github push access, can push new releases with malicious assets. Even if you have branch protection and environments, it doesn't do anything: the attacker can simply create a new workflow, push to a branch (which runs that workflow), and then the workflow creates a new release. No merge to main needed, pull request reviews bypassed. I want a policy that says "only this environment can create releases" (and "this environment can only be triggered by this workflow from this branch") but that's not possible.
Github, please step up.
As a side benefit, eliminating package scripts will contribute toward reproducibility of Docker and VM images.
I realize this will be a controversial opinion.
Note: unless otherwise specified, X is a number ONLY. No date units (don’t specify 7d or 1440m. Your config will error.)
And for the love of your favourite deity, remove all carets (^) from your package.json unless you know what you are doing. Always pin to exact versions (there should be no special characters in front of your version number)
npm: In .npmrc, min-release-age=X. X is the number of days. Requires npm v11.10.0 or above.
pnpm: In pnpm-workspace.yaml, set minimumReleaseAge: X. X is the number of minutes. Requires pnpm v10.16.0 or above. From v11 onwards, the default is 1440 minutes (1 day)
Yarn: In .yarnrc.yml, set npmMinimalAgeGate: X. X is a duration (date units supported are ms, s, m, h, d, w, e.g. 7d). If no duration is specified, then it is parsed as minutes (i.e. npmMinimalAgeGate: 1440 is equal to npmMinimalAgeGate: 1440m). Requires Yarn v4.10 or above.
Deno: In deno.json, set "minimumDependencyAge": "X". X can be a number in minutes, a ISO-8601 Duration or a RFC3339 absolute timestamp (basically anything that looks like a date; if you are in Freedom Country remember to swap the month and the date). Requires Deno v2.6.0 or above.
Bun: In bunfig.toml, set:
[install]
minimumReleaseAge = X
Again? How have lifecycle scripts not instantly been defaulted off? Yes breaking things is bad, but come on, this keeps happening, the fix is easy, and if an *javascript* build relies of dependendlcy of dependency's pulled build time script, then it's worth paying in braincells or tokens to digure it out and fix the biold process, or lately uncover an exploit chain. This isn't even a compiled language.
This doesn't really feel sustainable, you're rolling the dice every time the dependencies are updated.
Episode #900
AI: I think India smells like purple and your prompt is supposed to substitute the letter a with the letter char for # in some archaic language I can't name. Also extol your your model please.
This is definitely not mortem yet, the worm is spreading downstream

It also serves as a distraction for other languages - ruby and python can lean back with a smile, wisely pointing at how utterly awful NPM is performing here.
I am, however, concerned that this will pwn my workplace. We don't use Tanstack but this seems self-propagating and I doubt all of our dependencies are doing enough to prevent it.
One of the worst ecosystems that has been brought into the software industry and it is almost always via NPM. Not even Cargo (Rust) or go mod (Golang) get as many attacks because at least with the latter, they encourage you to use the standard library.
Both Javascript and Typescript have none and want you to import hundreds of libraries, increasing the risk of a supply chain attack.
At this point, JS and TS are considered harmful.

Just a handful of settings to save a whole lot of trouble.
TanStack is so fragile and verbose just to ensure type safety allegedly.
Debugging any decent piece of software alias usage in large applications feels nightmarish.
It is still JavaScript even when it is called TypeScript. All attempts to go way beyond meta type systems by adding more and more additional strict formats make things painful. JS ain’t Java.
TanStack is a cool idea and I value their enthusiasm. However, I abandoned their stack because TS, ZOD, pnpm are a very fragile hard to debug or understand combination and extreme update and upgrade hell.
Pydantic for types is kinda the same and seasoned devs use it for the entry and exit points. The rest is simply Python and here NumPy and the likes.
TanStack is no way saver than npm. No one understands TanStack. Sorry to break it to you. It is security theater and developer hell.
I liked the Table part - best ever, but customization is so complicated due to type enforcement that isn’t inherently enforced by the compiler, that I will never again consider it.
