CVE-2023-42930
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 · uneditedThis issue was addressed with improved checks. This issue is fixed in macOS Ventura 13.6.3, macOS Sonoma 14.2, macOS Monterey 12.7.2. 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 · high confidenceThis macOS vulnerability allows an application to bypass file system protection mechanisms and modify protected parts of the file system. The issue stems from insufficient authorization checks that were improved in the patched versions.

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 installed macOS versionRun 'sw_vers -productVersion' in Terminal or click Apple menu > About This Mac to view the macOS version numberAffected if The version is 12.0 to 12.7.1, 13.0 to 13.6.2, or 14.0 to 14.1 (any version within the ranges >= 12.0 < 12.7.2, >= 13.0 < 13.6.3, or >= 14.0 < 14.2)
-
Verify System Integrity Protection statusRun 'csrutil status' in Terminal to check if SIP is enabled. Note: This check indicates the baseline protection that could be bypassed.Affected if SIP is disabled (the vulnerability allows bypassing protections even when SIP is enabled, but SIP being off increases risk)
You are affected if your macOS version falls within 12.0 to 12.7.1, 13.0 to 13.6.2, or 14.0 to 14.1, as these versions contain the insufficient authorization checks that allow protected file system modification.
