Denial Of Service (DoS)

basic-ftp is vulnerable to Denial Of Service DoS. The vulnerability is due to excessive backtracking in the Unix directory listing parser when processing crafted FTP responses, which allows a malicious or compromised FTP server to consume excessive CPU and block the Node.js event loop, causing a...

CVE-2026-102990 basic-ftp: Quadratic-time CPU denial of service in Client.list() Unix directory-listing parser (RE_LINE backtracking)

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 RELINE expression in src/parseListUnix.ts backtracks across adjacent variable-length owner and group field...
