CVE-2022-20295
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn ContentService, there is a possible way to check if an account exists on the device due to a missing permission check. This could lead to local information disclosure with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-202160584
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIn ContentService on Android-13, a missing permission check allows any application with user-level execution privileges to determine whether specific accounts exist on the device, leading to local information disclosure of account presence.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Android versionCheck the device's Android version in Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The Android version is exactly 13.0 (Android 13)
-
Confirm ContentService presenceCheck if the ContentService component exists on the device by searching for content provider with authority 'com.android.contacts' using 'content query --uri content://com.android.contacts' via ADBAffected if ContentService responds to queries without requiring authentication, indicating the missing permission check is present
-
Test account enumeration accessAttempt to query account information via ContentService without any special permissions. Use a test app or ADB command to query accounts without RUN_AS_USERTEST or other elevated permissionsAffected if The query successfully returns whether specific accounts exist on the device, revealing account presence information to an unprivileged application
The environment is affected if the device runs Android 13.0 (exactly version 13.0) and unprivileged applications can query the ContentService to determine whether accounts exist on the device.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper permission verification in ContentService to require appropriate authentication/authorization before revealing account existence information to calling applications.
