QUANTUM THREAT INTELLIGENCE

AV26-996: Another Citrix NetScaler Flaw Exploited, CVE-2026-88779 Added to CISA's KEV Catalog

Cyber Centre advisory AV26-996 covers CVE-2026-88779 in Citrix NetScaler ADC and NetScaler Gateway, including FIPS builds. Citrix indicates the flaw is exploited in the wild and CISA added it to its Known Exploited Vulnerabilities catalog on October 4, 2026. It is the third NetScaler CVE flagged since alert AL26-024 on September 27, so remote access gateways on NetScaler should be patched again and checked for signs of compromise.

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.
