CVE-2026-24056
pnpm has symlink traversal in file:/git dependencies
Description
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.
