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

CVE-2026-48054

Description

Summary

The OpenZeppelin Contracts Wizard generated Hardhat (test/test.ts) and Foundry (test/.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.
