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 input validation in some Zoom Apps before version 6.2.0 may allow an unauthenticated user to conduct a denial of service 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 · high confidence

A denial-of-service vulnerability exists in certain Zoom Apps versions prior to 6.2.0 due to improper input validation. An unauthenticated attacker with network access can send specially crafted input to the affected Zoom Apps, causing them to become unresponsive or crash.

MitigationUpgrade all Zoom Apps to version 6.2.0 or later. If immediate upgrading is not possible, consider restricting network access to the affected Zoom Apps until the update can be applied.

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 products
    On Windows, check Add/Remove Programs or the installation directory (typically C:\Users\%username%\AppData\Roaming\Zoom). On macOS, check /Applications for Zoom apps. List all installed Zoom applications.
    Affected if Any Zoom product from the affected list (Zoom Workplace Desktop, Zoom Meeting SDK, Zoom Rooms, Zoom Rooms Controller, Zoom Video SDK, or Zoom Workplace) is installed.
  2. Check installed Zoom version
    For Zoom Workplace Desktop/Zoom Rooms: Open the Zoom client, click your profile picture, then click 'Check for Updates' or go to About > Version. Alternatively, right-click the Zoom icon in taskbar and select 'Check for updates'. For SDK products, check the version referenced in the project dependencies or the DLL/file version properties.
    Affected if The displayed version number is less than 6.2.0 (for example, 6.1.10, 6.0.5, etc.).
  3. Verify Zoom Apps feature is in use
    In the Zoom client, look for the 'Apps' tab in the top ribbon or sidebar. Check if any third-party Zoom Apps have been added or are running. For Zoom Rooms, check if the Rooms client has integrated apps enabled. For SDK implementations, check if the application embeds or runs Zoom Apps functionality.
    Affected if Zoom Apps feature is enabled, configured, or any third-party apps are installed within the Zoom environment.
  4. Confirm network exposure
    Determine if the affected Zoom client or SDK has network connectivity. Check firewall rules allowing outbound connections from Zoom processes (zoom.exe, ZoomRooms.exe, etc.). For SDK implementations, review whether the application accepts external network input.
    Affected if The affected Zoom product has network access and can receive external input from unauthenticated attackers.

You are affected if any Zoom product from the affected list is installed with a version lower than 6.2.0 AND the Zoom Apps feature is enabled or in use, and the system has network exposure.
