Fortinet, Ivanti Patch Critical Vulnerabilities

By Ionut Arghire

AI Summary

Fortinet and Ivanti both issued patches for critical vulnerabilities on May 2026 Patch Tuesday, with successful exploitation capable of leading to arbitrary code execution and information disclosure. Both vendors have been frequent targets of nation-state threat actors in recent years — Ivanti VPN products in particular have been exploited in zero-day campaigns by groups including UNC5325 and Volt Typhoon. Security teams should prioritize these patches given the demonstrated history of rapid exploitation of critical flaws in both vendors' products.

Relevance score: 76.0/100
