CVE-2018-14986
As the querying of the vulnerable content provider app component can be performed silently in the background, a malicious app can continuously monitor the content provider to see if the current message in each conversation has changed to obtain new text…

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The Leagoo Z5C Android device with a build fingerprint of sp7731c_1h10_32v4_bird:6.0/MRA58K/android.20170629.214736:user/release-keys contains a pre-installed app with a package name of com.android.messaging (versionCode=1000110, versionName=1.0.001, (android.20170630.092853-0)) containing an exported content provider named com.android.messaging.datamodel.MessagingContentProvider. Any app co-located on the device can read the most recent text message from each conversation. That is, for each phone number where the user has either sent or received a text message from, a zero-permission third-party app can obtain the body of the text message, phone number, name of the contact (if it exists), and a timestamp for the most recent text message of each conversation. As the querying of the vulnerable content provider app component can be performed silently in the background, a malicious app can continuously monitor the content provider to see if the current message in each conversation has changed to obtain new text messages.
