QUANTUM THREAT INTELLIGENCE
Cyber Centre advisory AV26-978 covers an API authentication bypass in Cisco Catalyst SD-WAN Manager, tracked as CVE-2026-76504, which CISA added to its Known Exploited Vulnerabilities catalog on September 30, 2026. SD-WAN Manager is the central configuration and policy console for an entire wide area network, so operators of branch, utility and carrier SD-WAN fabrics should update to the fixed releases promptly.
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.
