If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.)","published":"2020-08-11T21:15:11.000Z","lastModified":"2026-06-17T02:59:01.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},"cwe":["CWE-522"],"affected":["gnome/gnome-shell","canonical/ubuntu linux","debian/debian linux","opensuse/leap"],"epss":{"score":0.00553,"percentile":0.45956,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.55%).
