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 Safari version on macOSOpen Safari, go to Safari menu > About Safari, or run 'defaults read /Applications/Safari.app/Contents/Info CFBundleShortVersionString' in TerminalAffected if Version is lower than 18.4
-
Check iOS version on iPhoneGo to Settings > General > About on the iPhone deviceAffected if Version is lower than 18.4
-
Check iPadOS version on iPadGo to Settings > General > About on the iPad deviceAffected if Version is lower than 18.4
-
Check visionOS version on Apple VisionGo to Settings > General > About on the Apple Vision deviceAffected if Version is lower than 2.4
-
Check macOS versionGo to System Settings > General > About, or run 'sw_vers -productVersion' in TerminalAffected if Version is 15.0, 15.1, 15.2, or 15.3 (i.e., macOS Sequoia 15.0 through 15.3)
If the installed Safari, iOS, iPadOS, visionOS, or macOS version falls within the affected ranges (Safari/iOS/iPadOS < 18.4, visionOS < 2.4, macOS 15.0-15.3), the environment is vulnerable to unauthorized Local Network access.
