AV26-1112: Barracuda ADC, WAF and Security Gateways Carry Pre-Authentication Bypass and Command Injection

The Cyber Centre's AV26-1112, dated November 2, 2026, relays Barracuda's advisory on pre-authentication authorization bypass and command injection vulnerabilities in the Email Security Gateway, Load Balancer ADC, Web Application Firewall, Web Security Gateway, Message Archiver and WAF Control Center.

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.
