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 confidenceThis is a macOS permissions vulnerability where an application could improperly access sensitive user data due to insufficient access restrictions. The fix in macOS Sequoia 15.7.2, Sonoma 14.8.2, and Tahoe 26.1 adds additional permission controls to prevent unauthorized access to sensitive user data.

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.
-
Identify installed macOS versionOpen System Settings > General > About, or run 'sw_vers' in TerminalAffected if Version is 14.0 to 14.8.1 (Sonoma) or 15.0 to 15.7.1 (Sequoia)
-
Confirm macOS name and build numberRun 'uname -a' and 'system_profiler SPSoftwareDataType' to get detailed OS informationAffected if Build date corresponds to an affected release prior to the patches
-
Verify if sensitive data access permissions existCheck System Settings > Privacy & Security for any recently added permission prompts or restrictionsAffected if Older permission model is in use without the additional controls added in 14.8.2/15.7.2
The environment is affected if macOS version is 14.0 through 14.8.1 (Sonoma) or 15.0 through 15.7.1 (Sequoia), as these versions lack the additional permission controls added in the fixed releases.

dbcve · scoped14.8.215.7.2
Update macOS devices to version 15.7.2 (Sequoia), 14.8.2 (Sonoma), or 26.1 (Tahoe) or later to apply the permission restrictions fix.
macOS Sonoma 14.8.2 or macOS Sequoia 15.7.2 (depending on current major version)
- Back up important data before performing any system update
- Check the current macOS version by clicking the Apple menu and selecting 'About This Mac'
- Open System Settings and go to General > Software Update
- Allow the system to check for available updates
- If running macOS 14.x (Sonoma): Look for and install 'macOS Sonoma 14.8.2' security update
- If running macOS 15.x (Sequoia): Look for and install 'macOS Sequoia 15.7.2' security update
- Restart the Mac when prompted to complete the installation
