Last modified Jun 17, 2026

CVE-2021-33057 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The QQ application 8.7.1 for Android and iOS does not enforce the permission requirements (e.g., android.permission.ACCESS_FINE_LOCATION) for determining the device's physical location. An attacker can use qq.createMapContext to create a MapContext object, use MapContext.moveToLocation to move the center of the map to the device's location, and use MapContext.getCenterLocation to get the latitude and longitude of the current map center.. EPSS estimates a 1.00% chance of exploitation in the next 30 days.
