CVE-2023-41070
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 logic issue was addressed with improved checks. This issue is fixed in macOS Ventura 13.6, iOS 16.7 and iPadOS 16.7, watchOS 10, iOS 17 and iPadOS 17, macOS Sonoma 14. An app may be able to access sensitive data logged when a user shares a link.
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 a logic flaw in Apple's share functionality where an app can access sensitive data that gets logged when a user shares a link. The vulnerability stems from insufficient access controls on the logged data, allowing unauthorized apps to read information that should be protected during the link sharing process.

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 or iPadOS versionGo to Settings > General > About on iPhone or iPad, or check the model and iOS version via iTunes/Finder when connected to a computerAffected if The installed iOS version is below 16.7 or iPadOS version is below 16.7
-
Check macOS versionClick the Apple menu > About This Mac to view the macOS version numberAffected if The installed macOS version is 13.0 through 13.5 (Ventura 13.6+ is fixed)
-
Check watchOS versionOpen the Watch app on iPhone, select your watch, then go to General > About to view watchOS versionAffected if The installed watchOS version is below 10.0

Understand the vulnerability contextThis is a logic flaw in the built-in share sheet - no user-configurable setting exists to verify. The flaw allows any app with certain permissions to access sensitive data that gets logged during link sharing.Affected if Your device runs a vulnerable OS version and you use the share functionality to share links with third-party apps
You are affected if your device runs iOS/iPadOS below 16.7, macOS 13.0-13.5, or watchOS below 10.0, and you use the share sheet to share links with applications.
