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
SONY Wireless Headphones WF-1000X, WF-SP700N, WH-1000XM2, WH-1000XM3, WH-CH700N, WH-H900N, WH-XB700, WH-XB900N, WI-1000X, WI-C600N and WI-SP600N with firmware versions prior to 4.5.2 have vulnerability that someone within the Bluetooth range can make the Bluetooth pairing and operate such as changing volume of the product.

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

A Bluetooth pairing vulnerability in multiple Sony wireless headphone models with firmware versions prior to 4.5.2 allows unauthenticated attackers within Bluetooth range to pair with the device and perform operations such as changing volume. The CVSS 8.8 indicates a high-severity network-adjacent attack with moderate complexity.

MitigationUpdate the affected headphones firmware to version 4.5.2 or later using the Sony Headphones Connect app or official firmware update mechanism.

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 your Sony headphone model
    Locate the model name on the headphones themselves (usually on the ear cups or inside the headband) or check your purchase documentation/box. Confirm it matches one of: WF-1000X, WF-SP700N, WH-1000XM2, WH-1000XM3, WH-CH700N, WH-H900N, WH-XB700, WH-XB900N
    Affected if The model is one of the eight affected models listed in the CVE
  2. Check the installed firmware version
    Open the Sony Headphones Connect app on your smartphone, select your connected headphones, and navigate to the firmware or device information section. Alternatively, check your device Bluetooth settings if the version is displayed there
    Affected if The displayed firmware version is lower than 4.5.2 or cannot be determined (all versions before 4.5.2 are affected)
  3. Verify Bluetooth pairing behavior
    Observe whether the headphones enter pairing mode easily (e.g., holding the power button for a few seconds triggers pairing mode without requiring any app or PIN confirmation). This is the vulnerable behavior described in the CVE
    Affected if The headphones allow unauthenticated Bluetooth pairing without requiring a PIN or app-based authentication
  4. Confirm attack surface exposure
    Consider whether your headphones are typically used in public or shared spaces where unknown Bluetooth devices could be within range (typically 10 meters for Bluetooth)
    Affected if The headphones are used in environments where untrusted devices could be within Bluetooth range while the headphones are in pairing mode

You are affected if you own any of the eight listed Sony headphone models and your current firmware version is below 4.5.2, as all prior versions contain the unauthenticated Bluetooth pairing vulnerability.
