CVE-2022-42816
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 state management. This issue is fixed in macOS Ventura 13. An app may be able to modify protected parts of the file system.
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 confidenceCVE-2022-42816 is a logic flaw in macOS where improper state management allows a malicious or compromised application to bypass file system protections and modify typically restricted directories. This represents a privilege escalation issue where an app can access protected parts of the file system beyond its intended sandbox constraints.

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 the installed macOS versionRun 'sw_vers -productVersion' in Terminal or select Apple menu > About This MacAffected if The version displayed is less than 13.0 (any build of macOS Monterey 12.x or earlier)
-
Verify system integrity protection statusRun 'csrutil status' in Terminal to check if SIP is enabledAffected if SIP is disabled (the vulnerability requires system state management to be active)
-
Identify applications with full disk accessCheck System Settings > Privacy & Security > Full Disk Access for unexpected or untrusted applicationsAffected if A malicious or compromised app with Full Disk Access is present on the system
-
Review sandbox restrictionsRun 'spctl --master-status' to check system policy security statusAffected if The system allows apps with overridden sandbox policies to execute
The environment is affected if the macOS version is below 13.0 AND a malicious or compromised application can run with elevated permissions that interact with protected file system state.
