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 · unedited
This issue was addressed by removing additional entitlements. This issue is fixed in GarageBand 10.4.3. A local attacker may be able to read sensitive information.

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 confidence

A local entitlement misconfiguration in GarageBand allowed unprivileged local users to read sensitive information due to excessive entitlements. The fix involved removing these additional entitlements in version 10.4.3.

MitigationUpdate GarageBand to version 10.4.3 or later to receive the patched entitlements configuration.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if GarageBand is installed
    Open Finder, go to the Applications folder, and look for GarageBand.app. Alternatively, run: ls -la /Applications/ | grep -i garageband
    Affected if GarageBand.app is not present in the Applications folder
  2. Determine the installed GarageBand version
    Run the following command in Terminal: defaults read /Applications/GarageBand.app/Contents/Info.plist CFBundleShortVersionString
    Affected if The version shown is lower than 10.4.3 (for example, 10.4.2, 10.4.1, etc.)
  3. Verify the exact build version for clarity
    Run: mdls -name kMDItemVersion /Applications/GarageBand.app
    Affected if The build version returned is less than 10.4.3

You are affected if GarageBand is installed and its version (CFBundleShortVersionString) is below 10.4.3, as the vulnerable entitlement configuration was present in earlier versions.
