CVE-2026-48054 (GCVE-0-2026-48054)

Title

OpenZeppelin Contracts Wizard has Code Injection in Generated Hardhat and Foundry Tests via Unsanitized opts.name / opts.uri

Summary

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.

Vulnerability from github – Published: 2026-06-11 13:27 – Updated: 2026-06-11 13:27

Summary

OpenZeppelin Contracts Wizard has Code Injection in Generated Hardhat and Foundry Tests via Unsanitized opts.name / opts.uri

Details

Summary

The OpenZeppelin Contracts Wizard generated Hardhat (test/test.ts) and Foundry (test/<Name>.t.sol) example test files that interpolated user-supplied strings (opts.name, opts.uri) into the test source without escaping. A crafted input could produce a generated test file in which the input string broke out of its surrounding literal and was parsed as code, executing when a developer ran npm test or forge test on the downloaded project.

Impact

Users of the hosted Wizard at https://wizard.openzeppelin.com: no action required. The site has been redeployed with the fix.
Users of @openzeppelin/wizard via the documented public API: not affected. The vulnerable functions (zipHardhat, zipFoundry) are not part of the package's documented public exports.
Callers of zipHardhat / zipFoundry who forward externally-controlled strings into opts.name / opts.uri: upgrade to 0.10.9.

Patches

Fixed in @openzeppelin/wizard@0.10.9.

Severity

8.8 (High)
