@pnpm/fetching.binary-fetcher

A fetcher for binary archives

Installation

pnpm add @pnpm/fetching.binary-fetcher

Testing

Test Fixtures

The test/fixtures/ directory contains malicious ZIP files for testing path traversal protection:

File	Entry Path	Purpose
path-traversal.zip	../../../.npmrc	Tests ../ escape sequences
absolute-path.zip	/etc/passwd	Tests absolute path entries
backslash-traversal.zip	..\..\..\evil.txt	Tests Windows backslash traversal (Windows-only)

These fixtures are manually crafted because AdmZip's addFile() sanitizes paths automatically.

Note: The backslash test only runs on Windows because \ is a valid filename character on Unix.

Regenerating Fixtures
