Citrix NetScaler security snafus get even worse amid more 0-day reports

Citrix’s latest NetScaler zero-day, CVE-2026-88779, is already being exploited in the wild and can knock affected SAML-enabled appliances offline, creating immediate business risk by disrupting authentication and blocking users from reaching critical applications. For CIOs and technology leaders, this is another reminder that internet-facing edge devices can become enterprise-wide single points of failure, making rapid patching, exposure inventory, and mitigation execution core operational priorities rather than routine security tasks.
