CVE-2019-17123 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. (Also, the message parameter can have initial HTML comment characters.). EPSS estimates a 0.98% chance of exploitation in the next 30 days.
