CVE-2022-27817

Cross-session keystroke disclosure via device-level input capture

Published Apr 14, 2022 · Updated Aug 3, 2024

Exposure of keyboard input in SWHKD 1.1.5 and earlier allows local users to intercept keystrokes from other sessions. The privileged daemon listens for events from every keyboard input device without restricting capture to the initiating user's active Wayland session. Exploitation requires a low-privileged local account and concurrent activity in another session; recognized hotkeys are discarded, disrupting that session.
