Bug ID: 420802 Summary: SECURITY: Notification background "bleeds" into the lock screen Product: kde Version: unspecified Platform: Fedora RPMs OS: Linux Status: REPORTED Severity: major Priority: NOR Component: general Assignee: unassigned-b...@kde.org Reporter: chkb...@safe-mail.net Target Milestone: --- Created attachment 128029 --> https://bugs.kde.org/attachment.cgi?id=128029&action=edit Bug Screenshot SUMMARY The background of a notification will "bleed" into the lock screen, especially if the notification has blurred or glass effects. PRE-REQUISITES FOR REPRODUCING: 1. Noticed predominantly with a glass theme, especially with blurred effects. 2. Using a theme called "OxygenDymAero7." 3. Noticed on KDE Wayland session. STEPS TO REPRODUCE 1. Lock the screen 2. Trigger a notification, such as an update being available. The order of the steps do not appear to matter. OBSERVED RESULT A section of the lock screen will either be blurred or display an appreciable portion of the background effect used by the window. EXPECTED RESULT The lock screen should NOT give away the positions or contents of ANY window. This is a security issue and may also be the root of other potential information leaks in other circumstances. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Workstation 32 (available in About System) KDE Plasma Version: 5.18.3 KDE Frameworks Version: 5.68.0 Qt Version: 5.13.2 ADDITIONAL INFORMATION KDE Wayland session. Unknown if this is related to just KWin (Wayland) or if there are other components at play. -- You are receiving this mail because: You are watching all bug changes.
