A three-zero-day chain cracks Ivanti Connect Secure to root and leaves no trace

On October 13, 2026, Ivanti patched CVE-2026-104935, an authentication bypass exploited as a zero-day on its Connect Secure VPN gateways, which Volexity ties to a three-flaw chain ending in root. The compromise leaves nothing the vendor’s integrity tool can see: patch on an emergency basis and verify every appliance forensically.
