is there a yarn alternative for npm audit? - security

Question

need pinned resolution feature of yarn, but also want to audit with npm audit? Is there a yarn alternative to npm audit? Or, alternately, will pinning resolutions of dependencies of dependencies work in npm?

Answer 1

Yarn doesn't have npm audit fix.
But here's how to do it by using npm – temporarily.
Generate a package-lock.json file without installing node modules
npm i --package-lock-only
Fix the packages and update the package-lock.json file
npm audit fix
Delete the yarn.lock file and convert package-lock.json file into yarn.lock
rm yarn.lock
yarn import
Delete the package-lock.json file
rm package-lock.json
For example:
yarn audit
38363 vulnerabilities found - Packages audited: 908342
Severity: 38352 Low | 11 Moderate
(I know. react-scripts is crazy...)
npm audit
npm ERR! code EAUDITNOLOCK
npm ERR! audit Neither npm-shrinkwrap.json nor package-lock.json found: Cannot audit a project without a lockfile
npm ERR! audit Try creating one first with: npm i --package-lock-only
npm i --package-lock-only
...

Answer 2

yarn audit / yarn install --audit has been available since yarn#1.12.0
https://github.com/yarnpkg/yarn/releases/tag/v1.12.0
Unfortunately no --fix option yet, but as workaround you can use https://www.npmjs.com/package/yarn-audit-fix

Answer 3

Yes, you can use yarn audit to audit for vulnerability but you can't fix the Vulnerabilities by using yarn audit fix as you can do in npm audit fix.
To fix the Vulnerabilities in yarn.lock file you have to reinstall the package(which is carrying the Vulnerability) to its newer version by using yarn add package_name
you can read the issue here => https://github.com/yarnpkg/yarn/issues/7075

Answer 4

I thinks that it's not ready on yarn. You can refer to the following issue.
https://github.com/yarnpkg/yarn/issues/5808

Answer 5

do a yarn audit and find the package(s) with vulnerabilities,
if they are in your package.json file
fix their version from there
else
they are dependencies of your packages so add this to package.json file
"resolutions": {
"**/package-name": "known-good-version",
"**/**/package-name": "known-good-version"
}

Answer 6

1st
Always use source control and check in your package.json as well as your yarn.lock and/or package-lock.json first and start with all committed files, so you can roll back if needed with ease.
How about a solution that does not add dependencies to your project (nor installing a third party library)?
yarn outdated # view
yarn audit # view
yarn install --audit # install
Prefer an interactive way to upgrade selectively with ease?
yarn upgrade-interactive
That might do all you require.
Oddly, you might find with a yarn audit following that command you still have some vulnerabilities not mentioned from the command yarn upgrade-interactive. In this case I'd first consider this:
yarn upgrade-interactive --latest
where that can be found
Still not quite good enough?
```
yarn upgrade --latest
```
I've seen a lot of other potential solutions, previously I'd just switch to npm from yarn temporarily as some users have suggested, then switch back to yarn. This has worked fine for me too. (Though annoying and not elegant)
There are packages out there that don't require install to run.
I haven't tried this one, it might be good too:
npm_config_yes=true npx yarn-audit-fix
ref
The key here is you are using npx to avoid installing as a dependency.
Many more solutions are possible. npm and yarn both are package managers, dependency management is a very difficult thing to do, automagically fixing these dependencies will always be a difficult problem to solve. Thus I recommend a little research on how they are actually solving these problems if you have the time. You might find yourself not liking how they do things.
Ultimately, as long as you can roll back you can try a lot of these out and see for yourself. Some packages severity might not need fixing, sometimes libraries do not have solutions available yet, then you need to consider removing their usage in your codebase. In theory, less is more, less dependency on libraries, which use libraries, which use libraries.... becomes a much smaller surface for attackers to target. Also, it's not advisable to use libraries from untrusted sources, npm, yarn and more cannot know everything, nor right away, so keep that in consideration too.

Answer 7

I created a script command into the package.json file to fix it. It creates a copy of yarn.lock as package-lock.json, removes the issues and then re-creates yarn.lock.
"resolve:security": "npm i --package-lock-only && npm audit fix && rm yarn.lock && yarn import && rm package-lock.json",
I hope it helps :)

Answer 8

You can use yarn audit as mentioned in the other answers, however, there is a different way to solve them...
You will need to add the resolution instruction to specify the version of the library that the vunerability was solved and the path of the dependency (because the library can be a dependency of another dependency, for example:
Considering part of some package.json below
{
"name": "project",
"version": "1.0.0",
"dependencies": {
"left-pad": "1.0.0",
"c": "file:../c-1",
"d2": "file:../d2-1"
},
"resolutions": {
"d2/left-pad": "1.1.1",
"c/**/left-pad": "^1.1.2"
}
}
More details can be checked directly in the documentation: Doc

Answer 9

Yarn doesn't support the fix at the moment,
Workaround
create a package-lock.json file using npm.
fix the packages
remove the package-lock.json.
.
npm i --package-lock-only
npm audit fix
rm package-lock.json
and start
yarn start

Answer 10

Yarn also has yarn audit mechanism, but it doesn't have yarn audit fix mechanism. So in most cases you have to fix these issues manually. This is how it works. For example we'll demonstrate it using minimist package:
Add a resolutions key in your package.json file:
Adding dependency(say minimist) directly as key value .This resolution will override minimist entirely in your project.
{
"resolutions": {
"minimist": "^1.2.5"
}
}
In most cases, there can be multiple dependencies in a project that use the same secondary dependency, however, they might use different versions of those dependencies. Thankfully, yarn/npm allows us to have selective dependency resolutions.
The format to define resolutions is the following:
/* package.json */
{
"resolutions": {
"<package>/**/<dependency>": "<version>"
}
}
Let’s say for example, we have a dependency A and B and both of them depend upon another dependency C.
Then our resolutions field would look like:
/* package.json */
{
"resolutions": {
"A/**/C": "2.0.3", // A works fine with the latest version of C
"B/**/C": "1.9.0" // latest stable version for C for dependency B
}
}
Let's further see how it works with an example of package-merge-lodash-4 package. If audit says that lodash#3.9.3 has vulnerabilities and suggests us to upgrade lodash#3.9.3 -> 4.17.12.
We can write our json file's resolutions only for the concerned package as below:
{
"resolutions": {
"package-merge-lodash-4/**/lodash": "4.17.12"
}
}
How to use Selective dependency resolutions in npm?
add npm-force-resolutions to the preinstall script after you added resolutions key to package.json file, so that it patches the package-lock file before every npm install you run:
"scripts": {
"preinstall": "npx npm-force-resolutions"
}
To confirm that the right version was installed, use the below command
npm ls <vulnerable dependency>
npm ls lodash

Answer 11

Try using,
yarn upgrade-interactive --latest
Will install all the latest dependencies.
