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
Improper action enforcement in certain Zoom Workplace Clients for Windows may allow an unauthenticated user to conduct a disclosure of information via network access.

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 · low confidence

Improper action enforcement in Zoom Workplace Clients for Windows allows unauthenticated attackers on the network to access certain information due to missing or insufficient access controls on specific actions. The vulnerability enables information disclosure without requiring user authentication.

MitigationUpdate Zoom Workplace Client for Windows to the latest version containing the security fix. Until patched, restrict network access to untrusted networks and monitor for unusual access patterns.

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 installed Zoom product and version
    Open Windows Settings > Apps > Installed Apps, look for Zoom entries (Zoom Workplace, Zoom Rooms, Zoom Meeting SDK) and note the version number shown. Alternatively, open the Zoom client and go to Help > About to see the exact version.
    Affected if The installed version falls below 6.5.0 for Zoom Workplace Desktop, Zoom Rooms, Zoom Rooms Controller, or Zoom Meeting SDK; or below 6.4.12 (but above 6.4.0) or at 6.3.14 for Zoom Workplace VDI.
  2. Confirm product type matches affected list
    Determine which Zoom product is installed: Zoom Workplace Desktop (regular client), Zoom Rooms (conference room software), Zoom Rooms Controller (mobile controller app), Zoom Meeting SDK (developer kit), or Zoom Workplace VDI (virtual desktop).
    Affected if Any of these five products are installed at a vulnerable version.
  3. Assess network exposure to untrusted networks
    Check if the Zoom client runs on a system connected to networks where untrusted or anonymous attackers could be present (e.g., public WiFi, guest networks, internet-facing networks). Use ipconfig or network adapter status to identify network connectivity.
    Affected if The system is on a network where unauthenticated attackers could reach the Zoom client (local network segment, VPN split-tunneling, or direct internet exposure).

A defender is affected if they have any Zoom Workplace Desktop, Zoom Rooms, Zoom Rooms Controller, Zoom Meeting SDK, or Zoom Workplace VDI installed at a version below the fixed releases AND the client is reachable by unauthenticated attackers on the same network.
