Code Execution Vulnerability in CarAppService Deserialization Logic

Summary

There exists a code execution vulnerability in the Car App Android Jetpack Library. CarAppService uses deserialization logic that allows construction of arbitrary java classes. This can lead to arbitrary code execution when combined with specific Java deserialization gadgets. An attacker needs to install a malicious application on victims device to be able to attack any application that uses vulnerable library. We recommend upgrading the library past version 1.7.0-beta02.
