{"id":"USN-8572-1","summary":"wget vulnerability","details":"It was discovered that Wget did not properly validate the IP address\nprovided in an FTP PASV response when operating in FTP passive mode. A\nremote attacker controlling a malicious FTP server, or an HTTP server\nthat redirects to an FTP URL, could possibly use this issue to redirect\nWget's data connection to an arbitrary address and perform server-side\nrequest forgery, potentially accessing localhost services or internal\nnetwork resources.","modified":"2026-07-21T13:20:13.642909213Z","published":"2026-07-20T19:12:11Z","related":["UBUNTU-CVE-2026-15146"],"upstream":["CVE-2026-15146","UBUNTU-CVE-2026-15146"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8572-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-15146"}],"affected":[{"package":{"name":"wget","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/wget?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.15-1ubuntu1.14.04.5+esm3"}]}],"versions":["1.14-2ubuntu1","1.14-5ubuntu1","1.15-1ubuntu1","1.15-1ubuntu1.14.04.1","1.15-1ubuntu1.14.04.2","1.15-1ubuntu1.14.04.3","1.15-1ubuntu1.14.04.4","1.15-1ubuntu1.14.04.5","1.15-1ubuntu1.14.04.5+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"wget","binary_version":"1.15-1ubuntu1.14.04.5+esm3"}],"availability":"Available
