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 · unedited
In visitUris of Notification.java, there is a possible way to display images from another user due to a confused deputy. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

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 confidence

In Android's Notification.java, the visitUris method has a confused deputy vulnerability allowing a process to display images from another user's context without proper permission validation. This enables local information disclosure of potentially sensitive image data across user profiles without requiring user interaction or elevated privileges.

MitigationApply the Android security patch for CVE-2023-35668 (June 2023 Android Security Bulletin) to address the confused deputy issue in Notification.java's URI handling. Verify that notification images are properly scoped to the calling user's data.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Android version
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version
    Affected if Version is 11.0, 12.0, 12.1, or 13.0 (exact match)
  2. Check security patch level
    Run 'getprop ro.build.version.security_patch' or check Settings > About Phone > Security patch level
    Affected if Patch level is earlier than June 2023 (YYYY-06-01) or not set to the June 2023 patch date
  3. Verify notification image handling
    Review app notifications that include image URIs; the vulnerability affects any notification with image content loaded via URI in the affected Android versions
    Affected if Notifications with remote images are processed on an affected, unpatched Android version

You are affected if your Android device runs version 11.0, 12.0, 12.1, or 13.0 and has not received the June 2023 Android security patch.

Recommended fix Moderate confidence

Android 14 or later / Latest available security patch level

  1. 1. Navigate to Settings on the Android device
  2. 2. Go to System > Software Update (or Settings > About Phone > Software Update on some devices)
  3. 3. Check for and install any available system updates
  4. 4. Ensure the device is updated to Android 14 or later, which contains the fix for this vulnerability
  5. 5. Alternatively, ensure the device has the latest monthly security patch installed (available through your device manufacturer's security update)
Caveat Upgrading to a new Android major version may introduce UI changes or remove compatibility with older apps; ensure critical apps are compatible before upgrading
