CVE-2021-28117
libdiscover/backends/KNSBackend/KNSResource.cpp in KDE Discover before 5.21.3 automatically creates links to potentially dangerous URLs (that are neither https:// nor http://) based on the content of the store.kde.org web site.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
