EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 62% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

OpenZeppelin Contracts Wizard is 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.
