OpenZeppelin Contracts Wizardis a web application to interactively build a contract out of components from OpenZeppelin Contracts. Versions prior to 0.10.9 generate a Hardhat test file (`test/test.ts`) by interpolating user-supplied `opts.name` (ERC20/ERC721) and `opts.uri` (ERC1155) directly into TypeScript string literals at `zip-hardhat.ts:48` and `:50` without any JavaScript string escaping. No authentication is required: an attacker crafts a URL such as `https[:]//wizard[.]openzeppelin[.]com/#/erc20?name=");require("child_process").execSync("...");("` and shares it with a developer. When the victim downloads the resulting zip archive and runs `npx hardhat test`, the injected Node.js code executes with the developer's local OS privileges. Version 0.10.9 fixes the issue.
