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
An issue was discovered on certain Nuki Home Solutions devices. The HTTP API exposed by a Bridge used an unencrypted channel to provide an administrative interface. A token can be easily eavesdropped by a malicious actor to impersonate a legitimate user and gain access to the full set of API endpoints. This affects Nuki Bridge v1 before 1.22.0 and v2 before 2.13.2.

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 Nuki Bridge HTTP API uses an unencrypted channel (HTTP) to expose its administrative interface. Attackers on the same network can eavesdrop on API token traffic and intercept authentication tokens, then use those tokens to impersonate legitimate users and access the full set of API endpoints.

MitigationUpdate Nuki Bridge firmware to v1.22.0 or v2.13.2 or later, which implement encrypted communication. If immediate update is not possible, isolate the device on a trusted network segment.

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. Verify Nuki Bridge API accessibility over HTTP
    Attempt to access the Nuki Bridge API via HTTP (port 8080) using a curl or web browser request: curl -s http://<bridge-ip>:8080/info
    Affected if The Bridge responds successfully over HTTP, confirming unencrypted API access is enabled
  2. Verify HTTPS availability on the Bridge
    Attempt to access the Nuki Bridge API via HTTPS (port 8081): curl -k -s https://<bridge-ip>:8081/info
    Affected if The Bridge does NOT respond over HTTPS or the connection fails, indicating encrypted communication is not implemented
  3. Check the Bridge firmware version
    Query the Bridge API info endpoint over HTTP and look for the firmware version in the response: curl -s http://<bridge-ip>:8080/info | grep -i firmware
    Affected if The firmware version is below v1.22.0 for older hardware or below v2.13.2 (or if version cannot be determined and HTTP access is confirmed)
  4. Inspect network configuration for the Bridge
    Check the Bridge IP address and confirm it is on the same network segment as untrusted devices or a general LAN rather than an isolated VLAN
    Affected if The Bridge is on a shared network segment with untrusted devices and HTTP API access is confirmed

You are affected if the Nuki Bridge API is accessible over unencrypted HTTP and either HTTPS is unavailable or the firmware version is below v1.22.0/v2.13.2

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update Nuki Bridge firmware to v1.22.0 or v2.13.2 or later, which implement encrypted communication. If immediate update is not possible, isolate the device on a trusted network segment.

Recommended fix Moderate confidence

Nuki Bridge v1: upgrade to 1.22.0 or later; Nuki Bridge v2: upgrade to 2.13.2 or later

  1. Locate your Nuki Bridge device and identify its version (v1 or v2)
  2. Access the Nuki Bridge through the Nuki mobile app or web interface
  3. Check for firmware updates in the device settings
  4. Update to Nuki Bridge v1 version 1.22.0 or later, or v2 version 2.13.2 or later
  5. Verify the update was successful and the device is running the fixed firmware version
