Why pnpm no longer expands environment variables in a repository's .npmrc

pnpm used to expand $ placeholders everywhere it found them — including in the .npmrc and pnpm-workspace.yaml files that live inside the repository you just cloned. That turned out to be a way for a malicious repository to steal the secrets in your environment. As of v10.34.2 and v11.5.3, pnpm stops expanding environment variables in repository-controlled registry and credential settings.
