AV26-1133: SonicWall SonicOS Flaw CVE-2026-19868 Exploited, Added to CISA's KEV List, Patch Firewalls Now

On November 6, 2026 the Cyber Centre published AV26-1133 for SonicOS versions prior to 7.3.4-7013 and 8.2.2-8015. SonicWall reports CVE-2026-19868 is being exploited and CISA added it to the Known Exploited Vulnerabilities catalog the same day. SonicWall firewalls sit at the edge of many Canadian municipal, utility and credit union networks, so this is a patch now item, and a reminder that edge devices hold the keys that protect everything behind them.

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.
