Ubuntu 26.04 Wget Important Server-Side Request Forgery Vuln USN-8572-1

ubuntu
Calendar Grey July 20, 2026
Scroller Ubuntu
Address a Wget issue in Ubuntu which could allow unintended network connections, exposing internal resources.
Wget could be made to connect to unintended network resources.

Summary

Wget could be made to connect to unintended network resources.

Software Description:

- wget: retrieves files from the web

Details:

It was discovered that Wget did not properly validate the IP address

provided in an FTP PASV response when operating in FTP passive mode. A

remote attacker controlling a malicious FTP server, or an HTTP server

that redirects to an FTP URL, could possibly use this issue to redirect

Wget's data connection to an arbitrary address and perform server-side

request forgery, potentially accessing localhost services or internal

network resources.
