SCA: security update for basic-ftp (GHSA-rpmf-866q-6p89)

high Tenable Cloud Security Plugin ID 441371

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - basic-ftp is an FTP client for Node.js. Prior to 5.3.1, basic-ftp is vulnerable to client-side denial of
 service when parsing FTP control-channel multiline responses. A malicious or compromised FTP server can
 send an unterminated multiline response during the initial FTP banner phase, before authentication. The
 client keeps appending attacker-controlled data into FtpContext._partialResponse and repeatedly reparses
 the accumulated buffer without enforcing a maximum control response size. As a result, an application
 using basic-ftp can remain stuck in connect() while memory and CPU usage grow under attacker-controlled
 input. This can lead to process-level denial of service, container OOM kills, worker restarts, queue
 backlog, or service degradation in applications that automatically connect to FTP endpoints. This
 vulnerability is fixed in 5.3.1. (CVE-2026-44240)

Solution

Update the basic-ftp library and its related packages to version 5.3.1 or later.
