The basic-ftp FTP client library for Node.js contains a path traversal vulnerability (CWE-22) in versions prior to 5.2.0 in the downloadToDir() method. A malicious FTP server can send directory listings with filenames containing path traversal sequences (../) that cause files to be written outside the intended download directory. Version 5.2.0 patches the issue.
