pnpm has Path Traversal via arbitrary file permission modification

Summary When pnpm processes a package's directories.bin field, it uses path.join without validating the result stays within the package root. A malicious npm package can specify "directories": "bin": "../../../../tmp" to escape the package directory, causing pnpm to chmod 755 files at arbitrary...

GHSA-6PFH-P556-V868 pnpm: Binary ZIP extraction allows arbitrary file write via path traversal (Zip Slip)

Summary A path traversal vulnerability in pnpm's binary fetcher allows malicious packages to write files outside the intended extraction directory. The vulnerability has two attack vectors: 1 Malicious ZIP entries containing ../ or absolute paths that escape the extraction root via AdmZip's...

pnpm has Windows-specific tarball Path Traversal

Summary A path traversal vulnerability in pnpm's tarball extraction allows malicious packages to write files outside the package directory on Windows. The path normalization only checks for ./ but not .. On Windows, backslashes are directory separators, enabling path traversal. This vulnerability...

GHSA-6X96-7VC8-CM3P pnpm has Windows-specific tarball Path Traversal

Summary A path traversal vulnerability in pnpm's tarball extraction allows malicious packages to write files outside the package directory on Windows. The path normalization only checks for ./ but not .. On Windows, backslashes are directory separators, enabling path traversal. This vulnerability...

Directory Traversal

Overview @pnpm/store.cafs is a content-addressable filesystem for the packages storage Affected versions of this package are vulnerable to Directory Traversal via improper path normalization during tarball extraction on Windows. An attacker can overwrite files outside the intended directory by...

GHSA-XPQM-WM3M-F34H pnpm scoped bin name Path Traversal allows arbitrary file creation outside node_modules/.bin

Summary A path traversal vulnerability in pnpm's bin linking allows malicious npm packages to create executable shims or symlinks outside of nodemodules/.bin. Bin names starting with @ bypass validation, and after scope normalization, path traversal sequences like ../../ remain intact. Details Th...

Relative Path Traversal

Overview @pnpm/package-bins is a that returns bins of a package. Affected versions of this package are vulnerable to Relative Path Traversal via the commandsFromBin function when performing bin name validation and normalization. An attacker can create or overwrite arbitrary files outside the...

pnpm has symlink traversal in file:/git dependencies

Summary When pnpm installs a file: directory or git: dependency, it follows symlinks and reads their target contents without constraining them to the package root. A malicious package containing a symlink to an absolute path e.g., /etc/passwd, /.ssh/idrsa causes pnpm to copy that file's contents...

GHSA-M733-5W8F-5GGW pnpm has symlink traversal in file:/git dependencies
