AnalysisAIv1 – Sep 15, 2026

Authenticated administrators of the HPE (Aruba) EdgeConnect SD-WAN Orchestrator web management interface can be tricked into running attacker-supplied script in their own browser session, exposing data handled by the management plane. The flaw is a cross-site scripting (CWE-79) issue rated CVSS 5.5 with a scope change (S:C), meaning the injected code runs in the victim's browser context rather than inside the orchestrator process itself. There is no public exploit identified at time of analysis and the issue does not appear on CISA KEV, but exploitation requires an already-authenticated account, so the practical risk depends heavily on how many privileged accounts exist and how well the UI is network-restricted.
