basic-ftp is an FTP client for Node.js. Prior to 6.2.1, Client.list() can be forced by a malicious or compromised FTP server to spend quadratic CPU time parsing a directory listing because the RE_LINE expression in src/parseListUnix.ts backtracks across adjacent variable-length owner and group fields when a long Unix-style line has a valid prefix but cannot satisfy the later size and date fields. parseList() selects a parser from the last nonblank line and then applies it to every line, so a normal final line can select the Unix parser while an earlier crafted line blocks the Node.js event loop and freezes the process. This issue is fixed in version 6.2.1.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - basic-ftp is an FTP client for Node.js. Prior to 6.2.1, Client.list() can be forced by a malicious or
    compromised FTP server to spend quadratic CPU time parsing a directory listing because the RE_LINE
    expression in src/parseListUnix.ts backtracks across adjacent variable-length owner and group fields when
    a long Unix-style line has a valid prefix but cannot satisfy the later size and date fields. parseList()
    selects a parser from the last nonblank line and then applies it to every line, so a normal final line can
    select the Unix parser while an earlier crafted line blocks the Node.js event loop and freezes the
    process. This issue is fixed in version 6.2.1. (CVE-2026-102990)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
