Code Injection in @openzeppelin/wizard (CVE-2026-48054)
Summary
Code injection in @openzeppelin/wizard (CVE-2026-48054). Successful exploitation can lead to full system takeover. Exploitable via opts.name. Mitigation: upgrade to 0.10.9 or later.
Original description
The description as published by the source.
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/wizardvia the documented public API: not affected. The vulnerable functions (zipHardhat,zipFoundry) are not part of the package's documented public exports. - Callers of
zipHardhat/zipFoundrywho forward externally-controlled strings intoopts.name/opts.uri: upgrade to0.10.9.
Patches
Fixed in @openzeppelin/wizard@0.10.9.
