The issue allowed apps with Bluetooth access to record audio using connected AirPods, potentially capturing conversations with Siri and background sound. This was possible due to a problem with Core Bluetooth and the DoAP service, which supports Siri and Dictation on AirPods. The issue did not require the app to request microphone access permission and would not leave any traces of microphone eavesdropping. The vulnerability could be exploited to bypass the Transparency, Consent and Control (TCC) security system in macOS, allowing any app to record Siri conversations without requesting permissions.
