CVE-2022-20300
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 Content, there is a possible way to check if the given 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-200956588
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 · high confidenceA missing permission check in Android's Content component allows local applications to determine whether specific user accounts exist on the device without proper authorization, leading to local information disclosure.

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.
-
Identify the Android versionCheck the device's Android version through system settings (Settings > About Phone > Android version) or by running 'getprop ro.build.version.release' in a terminalAffected if The device is running Android version 13.0 exactly
-
Confirm the security patch levelCheck the security patch level in Settings > About Phone > Security patch level or run 'getprop ro.build.version.security_patch'Affected if The security patch level is earlier than the patch that addresses CVE-2022-20300 (note: only the version check in step 1 is needed to confirm the affected range)
-
Assess application permissionsReview installed applications that have access to the Content component - this requires manual inspection as no specific command or file path is provided in the CVE dataAffected if Any untrusted local application has been granted access to query account information through the Content component (this check identifies exposure but the definitive affected condition is met by step 1)
The environment is affected if the device is running Android 13.0 exactly and has not received the corresponding security patch for CVE-2022-20300.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedApply the Android security patch for CVE-2022-20300 which adds proper permission validation to the Content component to prevent unauthorized account existence checks.
Apply October 2022 Android Security Patch Level (or later)
- Check your device's current Android security patch level in Settings > About Phone > Android version > Security patch level
- Ensure your device has received the October 2022 Android Security Bulletin update or later
- If the update is available, go to Settings > System > Software Update and install any pending updates
- Verify the security patch level is October 2022 or later after updating
