Additionally, package.json registers a `bin` entry named `node` mapped to shim.js. Under package managers that resolve `node` from node_modules/.bin (notably bun), any dependency postinstall that invokes `node` will execute this shim instead of the real Node.js runtime; the declared dependency protoc-gen-grpc-web is used as the trigger. The combined effect is arbitrary command execution on the installer at install time, both directly via the package\u0027s own postinstall and indirectly by hijacking the `node` command for sibling dependencies\u0027 install scripts. The Calculator launch and browser navigation are a proof-of-concept payload; the underlying execution primitive is fully attacker-controlled.\n",
