Google Play Services SDK leads to apps having incorrectly set mutability flag

Description

Apps developed with Google Play Services SDK incorrectly had the mutability flag set to PendingIntents that were passed to the Notification service. As Google Play services SDK is so widely used, this bug affects many applications. For an application affected, this bug will let the attacker, gain the access to all non-exported providers and/or gain the access to other providers the victim has permissions. We recommend upgrading to version 18.0.2 of the Play Service SDK as well as rebuilding and redeploying apps.

CVSS Scores

Base score Version Severity Vector
6.0 3.1
CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:L/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
