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 · high confidenceCVE-2019-8618 is a sandbox escape vulnerability in Apple's iOS, macOS, and watchOS operating systems. The flaw is a logic issue that allows a sandboxed process to circumvent sandbox restrictions, potentially enabling a malicious application to gain unauthorized access to system resources or capabilities outside its intended permission boundaries.

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 iPhone or iPadOpen Settings app, go to General, tap About, and note the version number displayed next to 'Version'Affected if The version shown is less than 12.2 (for example, 12.1.x or earlier)
-
Check macOS version on Mac computerClick the Apple menu in the top-left corner, select 'About This Mac', and view the version number under the macOS nameAffected if The version is earlier than 10.14.4 (for example, 10.14.3, 10.14.2, etc.)
-
Check watchOS version on Apple WatchOpen the Settings app on the Apple Watch, scroll to General, tap About, and read the watchOS versionAffected if The version displayed is less than 5.2 (for example, 5.1.x or earlier)
-
Identify if any sandboxed applications are in useNote that all applications downloaded from the App Store run in a sandbox by default on iOS and watchOS; on macOS, verify if any third-party applications are installed from outside the Mac App StoreAffected if Any sandboxed application is present on the device (this is the default state for most applications)
The system is affected if the installed iOS version is below 12.2, macOS version is below 10.14.4, or watchOS version is below 5.2, regardless of which sandboxed application is running.
