CVE-2022-42818
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 data protection. This issue is fixed in macOS Ventura 13. A user in a privileged network position may be able to track user activity.
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 confidenceA data protection vulnerability in macOS allowed a network attacker with privileged position (likely man-in-the-middle) to track user activity. This was addressed through improved data protection mechanisms in macOS Ventura 13.

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 versionOpen Terminal and run: sw_vers -productVersionAffected if The version returned is less than 12.6 (for example, 12.5.x, 12.4.x, or earlier)
-
Confirm exact version numberCompare your reported version against the affected range: versions prior to 12.6 are vulnerableAffected if Your version starts with 12.0, 12.1, 12.2, 12.3, 12.4, or 12.5
-
Verify patch statusCheck if macOS 12.6 or later security updates have been applied via System Settings > General > Software UpdateAffected if No update to 12.6 or later has been installed
You are affected if your macOS version is below 12.6, as the improved data protection mechanisms that block network-based activity tracking were only added in that release.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
