AirSnitch research shows Wi-Fi client isolation can be bypassed across vendors

AirSnitch shows Wi-Fi client isolation can be bypassed across home, work, airport, and coffee-shop networks, undermining a control meant to block client-to-client snooping and injection. The work identifies three attack paths—abusing GTK, gateway bouncing, and Machine-in-the-Middle—that can let an attacker inject packets, intercept traffic, or reach isolated clients. Because the techniques work across multiple vendors, they raise the risk that client isolation is a false sense of security unless implementations are standardized and hardened.

AirSnitch research exposes Wi-Fi client-isolation bypasses
Technical Analysis UpdateUC Riverside researchers with a KU Leuven collaborator presented AirSnitch at NDSS Symposium 2026, showing that Wi-Fi client isolation, also known as Access Point (AP) isolation or station isolation, can be bypassed on home, work, airport, and coffee-shop networks through abusing GTK, gateway bouncing, and a Machine-in-the-Middle approach. They reported that every router and network tested was vulnerable to at least one method, and that manufacturers were given more than 90 days to develop fixes before publication.
