pnpm is a package manager. Prior to version 10.28.2, 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 locations. This issue only affects Unix/Linux/macOS. Windows is not affected (fixBin gated by EXECUTABLE_SHEBANG_SUPPORTED). Version 10.28.2 contains a patch.
AnalysisAI
pnpm versions before 10.28.2 fail to validate the directories.bin field during package processing, allowing malicious packages to use path traversal (e.g., ../../../../tmp) to escape the package root and chmod 755 files at arbitrary locations on Unix-like systems. Public exploit code exists for this vulnerability. …
