Arbitrary network requests via crafted management link
Published Apr 1, 2026 · Updated Apr 1, 2026
SSRF in Cisco Nexus Dashboard and Nexus Dashboard Insights allows remote attackers to send requests through affected devices. Specific HTTP request handling fails to validate a crafted link before causing the device to send an arbitrary request to an attacker-controlled server. Exploitation requires an authenticated management-interface user to click the link; the click enables script execution in that interface context or access to sensitive browser data.
