GHSA-QRV3-253H-G69C pnpm: Path traversal in configDependencies env lockfile allows symlink creation outside node_modules/.pnpm-config

Summary pnpm accepts package names from the env lockfile configDependencies section and uses those names directly when creating config dependency symlinks under nodemodules/.pnpm-config. A malicious repository can commit a crafted pnpm-lock.yaml whose env-lockfile document contains a...
