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."}, {"lang": "es", "value": "pnpm es un gestor de paquetes. Antes de la versi\u00f3n 10.28.2, cuando pnpm instala una dependencia 'file:' (directorio) o 'git:', 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, '/etc /passwd', '~/.ssh/id_rsa') hace que pnpm copie el contenido de ese archivo en 'node_modules', filtrando datos locales. La vulnerabilidad solo afecta a las dependencias 'file:' y 'git:'. 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 '~/.aws/credentials', '~/.npmrc', '~/.ssh/id_rsa'.
