AnalysisAIv1 – Sep 15, 2026

Authentication controls protecting the web-based management interface of HPE Aruba EdgeConnect SD-WAN Orchestrator can reportedly be circumvented by a remote actor, allowing escalation to administrative privileges and full compromise of the orchestrator host that manages the SD-WAN fabric. Reported affected releases span EdgeConnect SD-WAN software 9.4.0 through 9.7.0, with no fix version disclosed in the supplied source data. No public exploit code and no CISA KEV entry were identified at time of analysis, and no EPSS score was supplied, so exploitation status is best treated as unconfirmed.
