CVE-2026-63456Network attack vector

Unauthenticated system access via spoofed HTTP headers

Published Aug 4, 2026 · Updated Aug 4, 2026

Authentication bypass in EdgeConnect SD-WAN Orchestrator allows remote attackers to access REST API functions through spoofed HTTP headers. HPE identifies the REST API interface and spoofed headers but does not disclose the header names or the authentication validation error. No account or user interaction is required; successful requests can view and modify system information that can contain sensitive data.
