Hi,

The following vulnerability was published for node-proxy-agents.

CVE-2026-39983[0]:
| basic-ftp is an FTP client for Node.js. Prior to 5.2.1, basic-ftp
| allows FTP command injection via CRLF sequences (\r\n) in file path
| parameters passed to high-level path APIs such as cd(), remove(),
| rename(), uploadFrom(), downloadTo(), list(), and removeDir(). The
| library's protectWhitespace() helper only handles leading spaces and
| returns other paths unchanged, while FtpContext.send() writes the
| resulting command string directly to the control socket with \r\n
| appended. This lets attacker-controlled path strings split one
| intended FTP command into multiple commands. This vulnerability is
| fixed in 5.2.1.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
