Doc Text:
A flaw was found in basic-ftp, an FTP client for Node.js. A malicious or compromised remote FTP server can exploit this vulnerability by sending an extremely large or never-ending directory listing response. This can cause the client process to consume an unbounded amount of memory, leading to instability or a crash, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-04-24 04:01:29 UTC
basic-ftp is an FTP client for Node.js. Versions prior to 5.3.0 are vulnerable to denial of service through unbounded memory growth while processing directory listings from a remote FTP server. A malicious or compromised server can send an extremely large or never-ending listing response to `Client.list()`, causing the client process to consume memory until it becomes unstable or crashes. Version 5.3.0 fixes the issue.
