Ubuntu is installed on a laptop. Within five minutes of inactivity, the
screen lock activates and locks the system. Computer is secured. 10
minutes later, my cat (her name is Loaf) comes up to the laptop and sits
down on the keyboard. This activates a screen reader. (Shortcut is Alt +
Super + S)
What I've expected:
Screen reader would start reading the contents of a lock screen
What happened:
Screen reader app started reading contents of a Brave Browser window that was
opened on my desktop. It read all tabs and proceeded reading the opened web
page.
I've reported this bug at secur...@ubuntu.org and got the following answer:
> Nice find - I am able to reproduce this locally in Ubuntu 22.04 LTS too
> - I suspect this is a vulnerability in gnome-shell as it is
> responsible for handling the lock screen in standard Ubuntu.
As per further directions, I'm posting this bug here and in gnome repo.
P.S. I expect Loaf being credited for this find. She really likes treats.
