Prior to 2026.7.1, release tar archives record mise/bin/mise with user and group ID 1001 and packaging/standalone/install.envsubst extracts and moves it without normalizing ownership, allowing a local user with those IDs to replace a root-installed executable, especially when MISE_INSTALL_PATH targets a shared location such as /usr/local/bin. This issue is fixed in version 2026.7.1."

Antes de la versión 2026.7.1, los archivos tar de la versión registran mise/bin/mise con ID de usuario y grupo 1001 y packaging/standalone/install.envsubst lo extrae y lo mueve sin normalizar la propiedad, permitiendo que un usuario local con esos ID reemplace un ejecutable instalado por root, especialmente cuando MISE_INSTALL_PATH apunta a una ubicación compartida como /usr/local/bin. Este problema está solucionado en la versión 2026.7.1."
