CVE-2017-16667: Backintime Project Backintime

High severity, CVSS 7.8. EPSS: 1.5% chance of exploitation in the next 30 days.

backintime (aka Back in Time) before 1.1.24 did improper escaping/quoting of file paths used as arguments to the 'notify-send' command, leading to some parts of file paths being executed as shell commands within an os.system call in qt4/plugins/notifyplugin.py. This could allow an attacker to craft an unreadable file with a specific name to run arbitrary shell commands.
