zx Uses Incorrectly-Resolved Name or Reference

CVE-2025-13437 / GHSA-w87r-vg9q-crqm

More information

Details

When zx is invoked with --prefer-local=, the CLI creates a symlink named ./node_modules pointing to /node_modules. Due to a logic error in src/cli.ts (linkNodeModules / cleanup), the function returns the target path instead of the alias (symlink path). The later cleanup routine removes what it received, which deletes the target directory itself. Result: zx can delete an external /node_modules outside the current working directory.

Severity

v8.8.0: — Pressure Tested

Compare Source

This release enhances the coherence between the ProcessPromise and the Streams API, eliminating the need for certain script-level workarounds.

✨ New Features

unpipe() — Selectively stop piping

You can now call .unpipe() to stop data transfer from a source to a destination without closing any of the pair. #​1302

const p1 = $`echo foo && sleep 0.1 && echo bar && sleep 0.1 && echo baz && sleep 0.1 && echo qux`
const p2 = $`echo 1 && sleep 0.15 && echo 2 && sleep 0.1 && echo 3`
const p3 = $`cat`

p1.pipe(p3)
p2.pipe(p3)

setTimeout(() => p1.unpipe(p3), 150)

const { stdout } = await p3
// 'foo\n1\nbar\n2\n3\n'

Many-to-one piping

Multiple sources can now stream into a single destination. All sources complete before the destination closes. #​1300

const $h = $({ halt: true })
const p1 = $`echo foo`
const p2 = $h`echo a && sleep 0.1 && echo c && sleep 0.2 && echo e`
const p3 = $h`sleep 0.05 && echo b && sleep 0.1 && echo d`
const p4 = $`sleep 0.4 && echo bar`
const p5 = $h`cat`

await p1
p1.pipe(p5)
p2.pipe(p5)
p3.pipe(p5)
p4.pipe(p5)

const { stdout } = await p5.run()
// 'foo\na\nb\nc\nd\ne\nbar\n'

Piping from rejected processes

Processes that exit with errors can now still pipe their output. The internal recorder retains their stream, status, and exit code. #​1296

const p1 = $({ nothrow: true })`echo foo && exit 1`
await p1

const p2 = p1.pipe($({ nothrow: true })`cat`)
await p2

p1.output.toString() // 'foo\n'
p1.output.ok         // false
p1.output.exitCode   // 1

p2.output.toString() // 'foo\n'
p2.output.ok         // false
p2.output.exitCode   // 1

Components versions

Since zx bundles third-party libraries without their package.jsons, their versions weren’t previously visible. You can now access them via the versions static map — including zx itself. #​1298 #​1295

import { versions } from 'zx'

versions.zx     // 8.7.2
versions.chalk  // 5.4.1

v8.7.2: — Copper Crafter

Compare Source

Stability and customizability improvements

• Handle nothrow option on ProcessPromise init stage #​1288

const o = await $({ nothrow: true })`\033`
o.ok      // false
o.cause   // Error

• Handle _snapshot.killSignal value on kill() #​1287

const p = $({killSignal: 'SIGKILL'})`sleep 10`
await p.kill()
p.signal  // 'SIGKILL'

• Introduced Fail class #​1285

import { Fail } from 'zx'

Fail.EXIT_CODES['2'] = 'Custom error message'
Fail.formatErrorMessage = (err: Error, from: string): string =>
  `${err.message} (${from})`

• Expose $ as type #​1283

import type { $, Options } from 'zx'

const custom$: $ = (pieces: TemplateStringsArray | Partial<Options>, ...args: any[]) => {
  // ... custom implementation
}

• Internal tweak ups #​1276 #​1277 #​1278 #​1279 #​1280 #​1281 #​1282 #​1286 #​1289

• Described the zx architecture basics. This section helps to better understand the zx concepts and internal logic, and will be useful for those who want to become a project contributor, make tools based on it, or create something similar from scratch. #​1290 #​1291 #​1292

v8.7.1: — Pipe Whisperer

Compare Source

Continues v8.7.0: handles new ps() corner case and improves $.kill mechanics on Windows #​1266 #​1267 #​1269 webpod/ps#14

v8.7.0: — Solder Savior

Compare Source

Important fixes for annoying flaky bugs

kill() 🐞

We've found an interesting case #​1262

const p = $`sleep 1000`
const {pid} = p // 12345
await p.kill()

If we kill the process again, the result might be unexpected:

await ps({pid}) // {pid: 12345, ppid: 67890, command: 'another command', ...}
p.kill()

This happens because the pid may be reused by the system for another process, so we've added extra assertions to prevent indeterminacy:

p.kill()  // Error: Too late to kill the process.
p.abort() // Error: Too late to abort the process.

ps() 🐛

• ps() uses wmic internally on Windows, it relies on fragile heuristics to parse the output. We have improved this logic to handle more format variants, but over time (in v9 maybe) we're planning to change the approach.

#​1256 #​1263 webpod/ps#12 webpod/ingrid#6

const [root] = await ps.lookup({ pid: process.pid })
assert.equal(root.pid, process.pid)
