on Node.js NPM

Patch Changes

• 352ae48: Security: validate config dependency names and versions before using them to build filesystem paths. A pnpm-workspace.yaml with a traversal-shaped configDependencies name (such as ../../PWNED) or version (such as ../../../PWNED) could previously cause pnpm install to create symlinks or write package files outside node_modules/.pnpm-config and the store. Names must now be valid npm package names and versions must be exact semver versions. See GHSA-qrv3-253h-g69c.

• 352ae48: Reject path-traversal and reserved dependency aliases (such as ../../../escape, .bin, .pnpm, or node_modules) that come from a lockfile rather than a freshly resolved manifest. A crafted lockfile alias could otherwise be joined directly under a hoisted node_modules directory, letting package files be written outside the intended install root or overwrite pnpm-owned layout.

  The nodeLinker: hoisted graph builder now validates each alias at the directory sink (safeJoinModulesDir), matching the validation pnpm already performs when resolving aliases from manifests. See GHSA-fr4h-3cph-29xv.

• 352ae48: Prevent pnpm patch-remove from removing files outside the configured patches directory.

• 217fbe0: Hardened the warning printed when a project .npmrc uses environment variables in registry/auth settings: the suggested pnpm config set command is now only included for keys made up of shell-inert characters. Because the key comes from a repository-controlled .npmrc and a shell expands $(...), backticks, and $VAR even inside double quotes, a crafted key could otherwise have turned the suggested copy-paste command into command execution.
