Fortinet urges urgent patching of exploited FortiMail zero-day

Fortinet's FortiMail email security gateway is under active exploitation through a previously unknown vulnerability, prompting urgent calls for administrators to apply patches immediately. Security researchers warn that email gateways are prized targets because compromising them gives attackers a foothold into corporate networks and access to sensitive mail traffic.
Why now: Active exploitation of a zero-day in widely deployed email security software puts organisations at immediate risk until they patch.
