description: An exploitable information disclosure vulnerability exists in the 'Secret Chats' functionality of Rakuten Viber on Android 9.3.0.6. The 'Secret Chats' functionality allows a user to delete all traces of a chat either by using a time trigger or by direct request. There is a bug in this functionality which leaves behind photos taken and shared on the secret chats, even after the chats are deleted. These photos will be stored in the device and accessible to all applications installed on the Android device.
