2026-003: Multiple Vulnerabilities in Citrix NetScaler and Citrix ADC
Citrix NetScaler ADC and Gateway flaws enable memory information disclosure and user session mix-up; no active exploitation is observed yet.
Citrix patched CVE-2026-3055 (CVSS 9.3), an out-of-bounds read that can expose sensitive memory on systems configured as a SAML Identity Provider, and CVE-2026-4368 (CVSS 7.7), a race condition causing user session mix-up on Gateway and AAA virtual server configurations. Affected builds include NetScaler ADC and Gateway versions prior to 14.1-66.59 and 13.1-62.23. At publication there was no public evidence of active exploitation; CERT-EU recommends prioritizing internet-facing appliances, applying the Global Deny List mitigation, and terminating all sessions after patching.

Protecting organizations from AI-assisted executive impersonation and invoice fraud
Microsoft tracked a campaign of over one million AI-crafted CEO-impersonation emails seeking ~$50,000 ACH payments with fabricated ServiceNow invoices.
Between August 3 and 5, Microsoft detected a campaign of more than one million fraud emails, 87.7% of them targeting US enterprise users, sent through multiple third-party email delivery service accounts. The actor impersonated CEOs, CFOs, and presidents of targeted companies, urging accounts payable staff to process an ACH payment of nearly $50,000. Lures layered executive impersonation, lookalike domains, a fabricated ServiceNow 'Annual Subscription' invoice personalized to the recipient, and forged forwarded email threads; Microsoft found no evidence ServiceNow or the referenced executives were compromised. Microsoft observed indicators consistent with generative AI-assisted template creation, while leftover inconsistencies such as missing forwarding headers and mismatched display names gave defenders detection cues.
