CVE-2026-76504 is a critical, actively exploited Cisco Catalyst SD-WAN Manager vulnerability that allows unauthenticated API access as the admin user. Horizon3 reverse engineered the flaw, and NodeZero® Rapid Response safely validates exposure.

Horizon3 researchers used Anthropic’s Mythos to uncover a chain of cryptographic weaknesses in Rejetto HFS, recover a predictable signing key, forge an admin session, and achieve remote code execution.

See Your Active Directory Passwords From an Attacker’s Perspective Join Horizon3 and Shaun Hunt, CIO of McKenney’s and a longtime NodeZero® customer, for a live conversation about Active Directory password exposure and how NodeZero AD Password Audit helps uncover credentials that could be targeted through password cracking, password spray, credential stuffing, and credential reuse.

CVE-2026-19490 is a critical Citrix NetScaler ADC and Gateway authentication bypass vulnerability included in CISA’s Known Exploited Vulnerabilities catalog. NodeZero® Rapid Response safely validates exposure.

See how a global automotive technology manufacturer used NodeZero to reduce testing overhead, cut comparable test runtime by 50%, and scale security validation across more than 230 sites.
