Hi,

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

CVE-2026-102990[0]:
| 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.


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