Summary
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.)
Exploit prediction
0.98% chance of exploitation in the next 30 days, higher than 62% of all scored CVEs (FIRST EPSS, 2026-11-08).
