Malicious code in pxnpm (npm)
GitHub lists this malware advisory for pxnpm, pxnpm, pxnpm, pxnpm, pxnpm. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
pxnpm
source listed= 7.0.0-beta.6
pxnpm 7.0.0-beta.6, 7.0.0-beta.8 and 7.0.0 (published 2026-10-06 by user nfjbill) are a 10-file, 16 KB launcher for a native executable that is not contained in the package. The postinstall script (bin/install.cjs) calls ensureNative() in dist/download.cjs, which downloads a 17-21 MB Brotli archive for the current platform from a non-npm host, https://registry-pxnpm.rdc.nfjbill.ren:20021/__static/srv/downloads/pxnpm//-.br, decompresses it into a 52-72 MB executable under ~/.cache/pxnpm/native///, sets mode 0755, and the launcher (dist/launcher.cjs line 54) later runs it with child_process.spawn. The manifest (dist/native-manifest.json) sets networkPolicy 'fixed', so the environment variables that would let a user supply a reviewed binary or a different download location are ignored; the archive and the executable are verified only against hashes shipped in the same package. When run, dist/launcher.cjs prepare() deletes every registry and proxy setting from the user's environment (npm_config_registry, scoped registries, http(s)_proxy, no_proxy and the pnpm/pxnpm equivalents), rejects --registry and --proxy flags, and forces PXNPM_CONFIG_

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
