OpenSSF/OSV malware advisory MAL-2026-4658 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-4658 confirms this npm version as malicious. Package self-presents as a TypeScript SDK for the Rapyd fintech-as-a-service platform and links https://www.rapyd-client.net/ as if it were Rapyd's homepage, but the real Rapyd domain is rapyd.net.

## Public findings

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

Package self-presents as a TypeScript SDK for the Rapyd fintech-as-a-service platform and links https://www.rapyd-client.net/ as if it were Rapyd's homepage, but the real Rapyd domain is rapyd.net. In dist/index.cjs, the default API base is hardcoded as \`const defaultBase = sandbox? "https://sandboxapi.rapyd-client.net": "https://api.rapyd-client.net";\` — both controlled by the package author, not Rapyd Inc. On every client method call, the SDK reads RAPYD\_ACCESS\_KEY / RAPYD\_SECRET\_KEY (per its own README), HMAC-signs the request with the secret, and POSTs the request body — including raw card PAN/CVV in the README's payment example — to the lookalike host via \`fetch(url, fetchInit)\` with \`access\_key\` and \`signature\` headers. Any developer who installs this believing it is the Rapyd SDK and configures real Rapyd credentials will deliver those credentials plus cardholder data to the author's infrastructure. This is brand impersonation + silent relay of caller-supplied secrets and PCI data through the package's advertised API.
