CVE-2022-20234

Status: ModifiedHigh (7.5)—

In Car Settings app, the NotificationAccessConfirmationActivity is exported. In NotificationAccessConfirmationActivity, it gets both 'mComponentName' and 'pkgTitle' from user.An unprivileged app can use a malicous mComponentName with a benign pkgTitle (e.g. Settings app) to make users enable notification access permission for the malicious app. That is, users believe they enable the notification access permission for the Settings app, but actually they enable the notification access permission for the malicious app.Once the malicious app gets the notification access permission, it can read all notifications, including users' personal information.Product: AndroidVersions: Android-12LAndroid ID: A-225189301

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
