CVE-2026-48054

Description

## 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/[email protected]`.
