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
The data collection SDK of the router web management interface caused the leakage of the token. This affects Xiaomi router AX1800rom version < 1.0.336 and Xiaomi route RM1800 root version < 1.0.26.

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

A token leakage vulnerability exists in the data collection SDK of the Xiaomi router AX1800 (rom version < 1.0.336) and RM1800 (root version < 1.0.26) web management interface. The vulnerability allows unauthenticated attackers to potentially obtain sensitive session tokens through the data collection component.

MitigationUpdate Xiaomi router AX1800 firmware to version 1.0.336 or higher, and RM1800 to version 1.0.26 or higher. If updates are unavailable, consider network segmentation to limit exposure of the router management interface.

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. Identify router model
    Check the physical device label or log into the web management interface to confirm the exact model number (AX1800 or RM1800)
    Affected if Model is Mi AX1800 or Mi RM1800
  2. Check AX1800 firmware version
    Log into the router web interface (typically at 192.168.31.1) and navigate to Status or System Settings to view the current firmware version, or run command 'nvram get ver' via SSH if available
    Affected if Firmware version is below 1.0.336 on AX1800
  3. Check RM1800 firmware version
    Log into the router web interface and navigate to Status or System Settings to view the current firmware version, or run command 'nvram get ver' via SSH if available
    Affected if Firmware version is below 1.0.26 on RM1800
  4. Verify web management interface exposure
    Check if the router web management interface (port 80/443) is accessible from the internet or untrusted network segments by reviewing firewall rules and port forwardings
    Affected if Web management interface is exposed to untrusted networks

A user is affected if they are running Xiaomi AX1800 firmware below 1.0.336 or RM1800 below 1.0.26 AND the router web management interface is accessible from an untrusted network.
