Security readout for executives and security teams
Plain-English summary
CVE-2023-42929 is an Apple macOS privacy issue. A local app may be able to access protected user data. Apple says the issue was fixed in macOS Sonoma 14 by improved checks. The provided sources do not name the protected data type, affected earlier versions, or any active exploitation.
Executive priority
Patch in the normal Apple security update cycle, with priority for high-sensitivity users. The issue can expose protected user data, but available evidence does not show active exploitation or remote compromise. Risk increases where users can run untrusted apps.
Technical view
This is a local macOS information-disclosure vulnerability with CVSS 3.1 score 5.5: AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N. It requires local app execution and user interaction, with high confidentiality impact and no stated integrity or availability impact. Apple lists the affected product as macOS and the fixed release as macOS Sonoma 14.
Likely exposure
Exposure is likely limited to Macs not confirmed to be on macOS Sonoma 14 or later, especially where users can install or run untrusted apps. The source bundle does not identify specific earlier macOS versions, components, or configuration conditions.
Exploitation context
The sources support a local app-based privacy bypass, not remote exploitation. KEV is false, and the bundle provides no evidence of exploitation in the wild, public exploit availability, or weaponized activity. Treat this as a data-confidentiality risk rather than a system takeover based on available evidence.
Researcher notes
Public details are sparse. Apple describes improved checks but does not identify the subsystem, protected data class, or affected version range beyond macOS with a fix in Sonoma 14. Avoid assuming TCC, sandbox, or privacy database behavior without additional primary-source evidence.
Mitigation direction
- Update eligible Macs to macOS Sonoma 14 or later per Apple guidance.
- Prioritize endpoints used by executives, developers, finance, legal, and privileged administrators.
- Restrict installation and execution of untrusted applications where operationally feasible.
- Use MDM reporting to identify Macs below the fixed release.
- Review Apple advisory updates for additional affected-version detail.
Validation and detection
- Inventory macOS versions across managed and unmanaged endpoints.
- Confirm target systems are running macOS Sonoma 14 or later.
- Check MDM compliance reports for devices missing the fixed release.
- Review endpoint telemetry for recently installed unknown or untrusted apps.
- Document exceptions where devices cannot be upgraded promptly.
