CVE-2025-30664
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 · uneditedCross-site scripting in some Zoom Workplace Apps may allow an authenticated user to conduct an escalation of privilege via local 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 · moderate confidenceCross-site scripting vulnerability in Zoom Workplace Apps allows an authenticated user to execute arbitrary JavaScript in the context of the application, potentially leading to privilege escalation through local access. The XSS likely exploits insufficient sanitization of user-supplied content or third-party data processed by the desktop application.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Zoom productCheck for installed Zoom applications on the system. Look for Zoom Workplace Desktop, Zoom Rooms, Zoom Rooms Controller, or Zoom Meeting SDK installations. On Windows, check Program Files for Zoom folder. On macOS, check Applications folder.Affected if Any Zoom Workplace, Zoom Rooms, or Zoom Meeting SDK product is installed
-
Check Zoom Workplace Desktop versionOpen Zoom Workplace Desktop app, click your profile picture or Help menu, select 'About Zoom' or 'Check for Updates' to display the current version number.Affected if Version is displayed as less than 6.4.0
-
Check Zoom Rooms versionAccess Zoom Rooms controller or admin interface. Navigate to Room Settings or Account Settings > Rooms to view the installed Zoom Rooms version.Affected if Version is less than 6.4.0
-
Check Zoom Workplace VDI versionIf using virtual desktop infrastructure, check the Zoom Workplace VDI client version through the VDI admin console or by viewing the client application info.Affected if Version is less than 6.3.10
-
Verify user authentication contextDetermine if the Zoom application is configured with user accounts that can log in. XSS requires an authenticated user session to exploit.Affected if Zoom application has authenticated user accounts configured
The environment is affected if any Zoom product (Workplace Desktop, Rooms, VDI, or Meeting SDK) is installed with a version lower than 6.4.0 (or 6.3.10 for VDI), and users authenticate to the application.
