CVE-2019-17123
The eGain Web Email API 11+ allows spoofed messages because the fromName and message fields (to /system/ws/v11/ss/email) are mishandled, as demonstrated by fromName header injection with a %0a or %0d character.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
