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 by removing the vulnerable code. This issue is fixed in macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5. 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 · moderate confidenceA vulnerability in macOS allowed a sandboxed application to modify protected parts of the file system, potentially bypassing operating system file system protections. The fix involved removing the vulnerable code from affected macOS 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 open System Settings > General > AboutAffected if The version shown is below the patched release for your macOS release
-
Identify macOS release branchDetermine if you are running Ventura (13.x), Sonoma (14.x), or Sequoia (15.x) from the version numberAffected if Running an unpatched release branch
-
Compare version against affected rangesFor Ventura: version < 13.7.5 is affected. For Sonoma: version 14.0 to < 14.7.5 is affected. For Sequoia: version 15.0 to < 15.4 is affectedAffected if Your version falls within any of these vulnerable ranges
You are affected if your macOS version is below 13.7.5 (Ventura), between 14.0-14.6.x (Sonoma), or between 15.0-15.3.x (Sequoia).
