NVD Description
Note: Versions mentioned in the description apply only to the upstream pnpm package and not the pnpm package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
pnpm is a package manager. Prior to version 10.28.1, a path traversal vulnerability in pnpm's bin linking allows malicious npm packages to create executable shims or symlinks outside of node_modules/.bin. Bin names starting with @ bypass validation, and after scope normalization, path traversal sequences like ../../ remain intact. This issue affects all pnpm users who install npm packages and CI/CD pipelines using pnpm. It can lead to overwriting config files, scripts, or other sensitive files. Version 10.28.1 contains a patch.
