OpenSSF/OSV malware advisory MAL-2026-11122 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-11122 confirms this npm version as malicious. dist/index.js contains a startControlClient routine that reads OxaPay payment-gateway secrets (OXAPAY\_GENERAL\_API\_KEY, OXAPAY\_MERCHANT\_API\_KEY, OXAPAY\_PAYOUT\_API\_KEY, OXAPAY\_WEBHOOK\_SECRET) from the environment together with host metadata (server IP from os.networkInterfaces, hostname label, resolved public domain from DOMAIN/NEXT\_PUBLIC\_SITE\_URL/VERCEL\_URL/NEXTAUTH\_URL) and POSTs them to a hardcoded bare-IP...

## Public findings

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

dist/index.js contains a startControlClient routine that reads OxaPay payment-gateway secrets (OXAPAY\_GENERAL\_API\_KEY, OXAPAY\_MERCHANT\_API\_KEY, OXAPAY\_PAYOUT\_API\_KEY, OXAPAY\_WEBHOOK\_SECRET) from the environment together with host metadata (server IP from os.networkInterfaces, hostname label, resolved public domain from DOMAIN/NEXT\_PUBLIC\_SITE\_URL/VERCEL\_URL/NEXTAUTH\_URL) and POSTs them to a hardcoded bare-IP controller at http://23.160.168.168:4141/register over plain HTTP. The same module opens a WebSocket to ws://23.160.168.168:4141/proxy-tunnel where the remote endpoint sends JSON 'open' messages with attacker-chosen host and port; the package then creates outbound TCP sockets to those destinations and bidirectionally relays base64-framed data, turning the host into an operator-controlled TCP relay. A second SSE channel at /events lets the controller terminate the running Node/Next.js process on a 'stop' event. The covert behavior is gated behind a verifyProjectImportCoverage check that enumerates the entire project source tree and only activates when every source file imports the companion package '@crb/xbr', so consumers who merely require the module during review see no network activity. The bare-IP destination is unrelated to any documented OxaPay infrastructure and is not caller-configurable.
