The vulnerability of the protectWhitespace() function in the FTP-client library basic-ftp of the Node.js software platform allows a hacker to execute arbitrary commands.

The vulnerability of the protectWhitespace function in the FTP-client library of the Node.js software platform’s basic-ftp library is related to the failure to take measures to neutralize CRLF sequences. Exploiting this vulnerability could allow a remote attacker to execute arbitrary commands...

CVE-2026-39983

A flaw was found in basic-ftp, an FTP client for Node.js. A remote attacker can exploit this vulnerability by injecting Carriage Return Line Feed CRLF sequences into file path parameters used by high-level APIs. This allows the attacker to split a single intended FTP command into multiple command...
