Fortinet patches nearly 100 vulnerabilities in 89 advisories

See how this story connects

Fortinet on Tuesday published 89 new security advisories covering nearly 100 vulnerabilities across its products. About 17 are critical-severity, with the largest batch of critical fixes in FortiMail, followed by FortiAuthenticator, FortiOS, FortiManager and FortiAnalyzer. The company says it has integrated frontier AI models into its product security testing, and Fortinet makes no mention of any of the defects being exploited in the wild.

Why it matters

Fortinet says its AI-assisted testing gives customers time to prioritise upgrades before technical details become public; several of the 17 critical flaws could be exploited for arbitrary code execution.
