CVE-2026-23810

Cross-BSSID traffic interception via GTK re-encryption

Published Mar 4, 2026 · Updated Mar 4, 2026

Improper packet handling in HPE Aruba Networking AOS-8 and AOS-10 allows attackers to intercept traffic across BSSID boundaries. An access point misclassifies a crafted Wi-Fi frame as group-addressed traffic and re-encrypts it with the victim BSSID's GTK, enabling GTK-independent injection. The attacker must be authenticated and within wireless range; port stealing is additionally required to redirect intercepted traffic for machine-in-the-middle attacks.
