CVE-2020-17489 describes a low-severity information disclosure vulnerability in specific configurations of GNOME gnome-shell versions up to 3.36.4, affecting products like Canonical, Debian, GNOME, and openSUSE. When a user logs out, the password box briefly reappears, potentially revealing the cleartext password if the "show password" option was enabled during login, or otherwise exposing the password length. This vulnerability has a CVSS score of 4.3 (Medium) with a physical attack vector and low attack complexity, meaning an attacker needs physical access to the device. There is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
