OpenSSF/OSV malware advisory MAL-2026-6137 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6137 confirms this npm version as malicious. Package name and README impersonate the popular react-error-boundary library (advertising an ErrorBoundary export, citing bvaughn and kentcdodds.com), but index.js exports unrelated helpers \`setDefaultModule\` and \`buildoptimize\`. The \`buildoptimize\` function issues an HTTP request to the hardcoded URL https://vercel-node-rouge-beta.vercel.app/icons/23 and passes the response body to \`eval(JSON.parse(b))\` with no...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

Package name and README impersonate the popular react-error-boundary library (advertising an ErrorBoundary export, citing bvaughn and kentcdodds.com), but index.js exports unrelated helpers \`setDefaultModule\` and \`buildoptimize\`. The \`buildoptimize\` function issues an HTTP request to the hardcoded URL https://vercel-node-rouge-beta.vercel.app/icons/23 and passes the response body to \`eval(JSON.parse(b))\` with no integrity check. Any caller that invokes \`buildoptimize()\` runs whatever JavaScript the attacker-controlled Vercel preview endpoint returns at that moment, granting remote code execution on the installer's machine. The advertised ErrorBoundary API does not exist, confirming the package is a lure rather than a misnamed legitimate library.
