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
Amazon Ring Doorbell before 3.4.7 mishandles encryption, which allows attackers to obtain audio and video data, or insert spoofed video that does not correspond to the actual person at the door.

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 confidence

The Amazon Ring Doorbell devices before firmware version 3.4.7 contain an encryption mishandling vulnerability that allows attackers to obtain audio and video data through improper cryptographic implementation. Attackers can also inject spoofed video that does not correspond to the actual person at the door, indicating both confidentiality and integrity impacts on the video stream.

MitigationUpdate Ring Doorbell firmware to version 3.4.7 or later to remediate the encryption vulnerability; verify that devices are running the patched version and on supported software lifecycles.

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 the installed firmware version
    Open the Ring mobile app, select the Ring Doorbell device, go to Device Settings, then Device Info, and locate the Firmware Version field. Alternatively, access the device through the Ring website and navigate to the device details page.
    Affected if The displayed firmware version is below 3.4.7 (for example, 3.4.6, 3.3.9, etc.)
  2. Check device health status
    In the Ring app, select the doorbell device and tap Device Health to view current status, signal strength, and firmware information.
    Affected if The firmware version shown in Device Health is less than 3.4.7 or shows as out of date
  3. Verify if firmware update is available
    In the Ring app, go to the device settings and check for any pending firmware updates. A device affected by this CVE would typically show an available update to version 3.4.7 or later.
    Affected if The app indicates a firmware update is available, suggesting the current version is older than the latest patched release

You are affected if your Ring Doorbell is running firmware version 3.4.6 or any version prior to 3.4.7, as these versions contain the encryption mishandling vulnerability that exposes audio and video data.

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 · scoped
Upgrade available Upgrade to 3.4.7 or later
Fixed in 3.4.7
Interim mitigation

Update Ring Doorbell firmware to version 3.4.7 or later to remediate the encryption vulnerability; verify that devices are running the patched version and on supported software lifecycles.

Recommended fix Moderate confidence

Firmware version 3.4.7

  1. Open the Ring mobile application and navigate to your device settings
  2. Locate the Ring Video Doorbell device in the device list
  3. Check the current firmware version under Device Settings or Device Info
  4. If firmware version is below 3.4.7, select the option to update firmware
  5. Ensure the doorbell is connected to a stable Wi-Fi network during the update
  6. Wait for the firmware download and installation to complete - do not disconnect power
  7. After the update finishes, verify the new firmware version displays 3.4.7 or higher
