CVE-2023-32358
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 · uneditedA type confusion issue was addressed with improved checks. This issue is fixed in iOS 16.4 and iPadOS 16.4, macOS Ventura 13.3. Processing web content may lead to arbitrary code execution.
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 confidenceA type confusion vulnerability in WebKit (the browser engine used by Safari and UIWebView) allows arbitrary code execution when processing malicious web content. This is a client-side vulnerability affecting iOS, iPadOS, and macOS devices.

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.
-
Check iOS version on iPhoneGo to Settings > General > About and look at the Version number. Compare to the affected range 16.0 to 16.4.Affected if Version starts with 16.0, 16.1, 16.2, or 16.3 (any 16.x prior to 16.4)
-
Check iPadOS version on iPadGo to Settings > General > About and look at the Version number. Compare to the affected range 16.0 to 16.4.Affected if Version starts with 16.0, 16.1, 16.2, or 16.3 (any 16.x prior to 16.4)
-
Check macOS version on MacClick the Apple menu > About This Mac. Look at the version number under macOS. Compare to the affected range 13.0 to 13.3.Affected if Version shows 13.0, 13.1, 13.2, or 13.3 (Ventura prior to 13.3)

Confirm WebKit-based browser or component usageIdentify if Safari is regularly used, or if third-party apps using UIWebView (iOS/iPadOS) or WebKit are in use. This vulnerability is triggered when processing malicious web content.Affected if Safari or any app using WebKit is used on a device running an affected OS version
The device is affected if it runs iOS/iPadOS 16.0-16.3 or macOS 13.0-13.2 and uses Safari or WebKit-based components to process untrusted web content.
