CVE-2022-20728 is a medium-severity vulnerability affecting Cisco Access Points, allowing an unauthenticated, adjacent attacker to inject packets from the native VLAN to clients in non-native VLANs. This logic error bypasses VLAN separation and potentially Layer 3 protections. The attack requires access to the native VLAN and direct targeting of a client's MAC/IP. There is no evidence of active exploitation, public exploit code, or significant community discussion, though it has received some media coverage.
