Legacy pairing and secure-connections pairing authentication in Bluetooth
BR/EDR Core Specification v5.2 and earlier may allow an unauthenticated
user to complete authentication without pairing credentials via adjacent
access. An unauthenticated, adjacent attacker could impersonate a Bluetooth
BR/EDR master or slave to pair with a previously paired remote device to
successfully complete the authentication procedure without knowing the link
key.
