AV26-1102: Cisco ASA and FTD SSL VPN Flaw CVE-2026-76418 Exploited in the Wild, Added to CISA's KEV List

Cisco Secure Firewall ASA and Firewall Threat Defense carry a remote access SSL VPN tunnel denial of service flaw, CVE-2026-76418, which Cisco says is exploited in the wild; CISA added it to the Known Exploited Vulnerabilities catalogue on October 29, 2026. Fixed releases span ASA 9.16 through 9.24 and FTD 7.0 through 10.1, and Smart Software Manager On-Prem is also affected. Canadian operators with ASA or FTD remote access VPN exposed to the internet should patch now and review what else terminates on those appliances.

Why this matters for your infrastructure

Every advance in quantum computing shortens the window for migrating long lived infrastructure off quantum-vulnerable encryption, and data captured today can be decrypted later. Fabric Networks helps energy, government, telecom and community networks move to quantum-safe encryption on their own timeline, not an adversary's.
