Overview

basic-ftp is a FTP client for Node.js, supports FTPS over TLS, IPv6, Async/Await, and Typescript.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the connect function. An attacker can cause excessive memory and CPU consumption, leading to application unavailability or service degradation, by sending an unterminated multiline FTP control response from a malicious or compromised FTP server before authentication. No user interaction or valid credentials are required for exploitation.
