CVE-2026-41324 · basic-ftp vulnerable to denial of service via unbounded memory consumption in Client.list()

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
