CVE-2026-24056

Date: January 26, 2026

pnpm is a package manager. Prior to version 10.28.2, 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/id_rsa") causes pnpm to copy that file's contents into "node_modules", leaking local data. The vulnerability only affects "file:" and "git:" dependencies. Registry packages (npm) have symlinks stripped during publish and are NOT affected. The issue impacts developers installing local/file dependencies andCI/CD pipelines installing git dependencies. It can lead to credential theft via symlinks to "~/.aws/credentials", "~/.npmrc", "~/.ssh/id_rsa". Version 10.28.2 contains a patch.
