It was found that the :source! command was not restricted by the sandbox mode. If modeline was explicitly enabled, opening a specially crafted text file in vim could result in arbitrary command execution.
Mitigation
The vulnerability can be triggered only if modeline is enabled. You can check whether modeline is enabled within vim via the command :set modeline?
It can be turned off explicitly by adding set nomodeline in a vimrc file.
