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 Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.12.2 is susceptible to a URL parsing vulnerability. If a malicious Zoom meeting URL is opened, the malicious link may direct the user to connect to an arbitrary network address, leading to additional attacks including session takeovers.

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

The Zoom Client for Meetings contains a URL parsing vulnerability across all major platforms (Android, iOS, Linux, macOS, Windows). When a user opens a maliciously crafted Zoom meeting URL, the client improperly parses the URL and may direct the user to connect to an arbitrary network address. This improper handling can lead to session takeovers and additional attacks.

MitigationUpgrade Zoom Client for Meetings to version 5.12.2 or later to remediate this vulnerability. Users should avoid clicking on untrusted or unsolicited Zoom meeting links.

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. Check Zoom Meetings client version
    Open the Zoom Meetings client, then navigate to the 'Help' menu and select 'About Zoom' to view the installed version number
    Affected if The displayed version is lower than 5.12.2
  2. Check Zoom Rooms for Conference Rooms version
    Access the Zoom Rooms controller or sign in to the Zoom Rooms web portal and locate the version information in the device settings or status area
    Affected if The installed version is lower than 5.12.2
  3. Check Zoom Virtual Desktop Infrastructure version
    Log into the Zoom VDI admin interface or check the version displayed in the VDI client connection window
    Affected if The version shown is lower than 5.12.2
  4. Compare all installed Zoom products against the threshold
    For each Zoom product deployed in your environment (client, rooms, VDI), record the exact version number and verify it meets or exceeds 5.12.2
    Affected if Any product is found to be below version 5.12.2

You are affected if any installed Zoom product (Meetings client, Zoom Rooms, or Zoom VDI) has a version number lower than 5.12.2, as the URL parsing flaw exists in those vulnerable versions.
