CVE-2021-41583
vpn-user-portal (aka eduVPN or Let's Connect!) before 2.3.14, as packaged for Debian 10, Debian 11, and Fedora, allows remote authenticated users to obtain OS filesystem access, because of the interaction of QR codes with an exec that uses the -r option.
Does this matter?
Lower severity and a low EPSS score (1.88%). Track it; it rarely justifies an emergency change on its own.
