Description Ritesh Raj Sarraf 2014-01-31 07:50:40 UTC
When using plasma on the lock screen, a user can bypass the lock screen and get access to the user's data (with the permissions inherited from the running user).

Reproducible: Always

Steps to Reproduce:
1. Lock your screen
2. Add a wallpaper / pictrue frame widget to your lock screen
3. Now right click to check the option "Save picture / wallpaper"
4. The file open window gives you full privileges of the running user.
Actual Results:  
Full access to the data using the File Open Interface

Expected Results:  
When called from the lock screen, the access should be limited.
