We found that Wi-Fi client isolation can often be bypassed. This allows an attacker who can connect to a network, either as a malicious insider or by connecting to a co-located open network, to attack others.

High-level article on the work by Dan Goodin: https://arstechnica.com/security/2026/02/new-airsnitch-attack-breaks-wi-fi-encryption-in-homes-offices-and-enterprises/ I'd say we bypass Wi-Fi encryption though, in the sense that we can bypass client isolation. We don't break Wi-Fi authentication or encryption. Crypto is often bypassed instead of broken. And we bypass it ;) If you don't rely on client/network isolation, you are safe: we can't just break any Wi-Fi network.
