Title
pnpm has symlink traversal in file:/git dependencies
Summary
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.

Antes de la versi\u00f3n 10.28.2, cuando pnpm instala una dependencia \u0027file:\u0027 (directorio) o \u0027git:\u0027, sigue los enlaces simb\u00f3licos y lee el contenido de sus destinos sin restringirlos a la ra\u00edz del paquete. Un paquete malicioso que contiene un enlace simb\u00f3lico a una ruta absoluta (por ejemplo, \u0027/etc /passwd\u0027, \u0027~/.ssh/id_rsa\u0027) hace que pnpm copie el contenido de ese archivo en \u0027node_modules\u0027, filtrando datos locales. La vulnerabilidad solo afecta a las dependencias \u0027file:\u0027 y \u0027git:\u0027. Los paquetes de registro (npm) tienen los enlaces simb\u00f3licos eliminados durante la publicaci\u00f3n y NO se ven afectados. El problema afecta a los desarrolladores que instalan dependencias locales/de archivo y a las tuber\u00edas de CI/CD que instalan dependencias de git. Puede conducir al robo de credenciales a trav\u00e9s de enlaces simb\u00f3licos a \u0027~/.aws/credentials\u0027, \u0027~/.npmrc\u0027, \u0027~/.ssh/id_rsa\u0027.
