CVE-2025-49463
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 · uneditedInsufficient control flow management in certain Zoom Clients for iOS before version 6.4.5 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 · moderate confidenceThis is an information disclosure vulnerability in Zoom's iOS client stemming from insufficient control flow management. An unauthenticated attacker with network access can potentially access sensitive information due to improper handling of control flow logic in versions prior to 6.4.5.

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 iOS client versionOpen the Zoom app on the iOS device, navigate to Settings > About > Version, or check the version listed in the App Store app listing under the Zoom appAffected if The displayed version number is lower than 6.4.5 (for example, 6.4.4, 6.3.0, etc.)
-
Check iOS device inventoryUse Mobile Device Management (MDM) software or manually review all iOS devices that have Zoom installed to determine which devices are running affected versionsAffected if Any managed iOS device has Zoom iOS client version prior to 6.4.5 installed
-
Verify Zoom app is configured for network communicationConfirm that the Zoom iOS app has been used to join meetings or sign in, which would establish network connectivity that an attacker could exploitAffected if The app has been used to join meetings or sign in, enabling network access that could be leveraged by an unauthenticated attacker
You are affected if any iOS device in your environment runs a Zoom client version lower than 6.4.5 and the app has been used for meetings or sign-in, allowing network-accessible attackers to potentially access sensitive information through the control flow vulnerability.
