CVE-2025-43266
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 · uneditedA permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia 15.6, macOS Sonoma 14.7.7, macOS Ventura 13.7.7. An app may be able to break out of its sandbox.
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 permissions vulnerability in macOS allowed a malicious application to escape its sandbox containment and potentially gain elevated privileges outside its intended isolation boundary. The issue was addressed through additional permission restrictions in the 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.
-
Identify installed macOS versionRun 'sw_vers -productVersion' in Terminal to get the exact macOS version number (e.g., 14.6.1)Affected if Version is lower than 13.7.7, or between 14.0-14.7.6, or between 15.0-15.5
-
Confirm macOS release nameRun 'sw_vers -productVersion' and check the major version: 13 = Ventura, 14 = Sonoma, 15 = SequoiaAffected if Release is Ventura with version < 13.7.7, or Sonoma with version < 14.7.7, or Sequoia with version < 15.6
-
Verify system is not patchedCompare your version from step 1 against the fixed versions: Ventura 13.7.7, Sonoma 14.7.7, or Sequoia 15.6Affected if Your version falls within any of the vulnerable ranges listed
System is affected if running any macOS version lower than 13.7.7 (Ventura), between 14.0-14.7.6 (Sonoma), or between 15.0-15.5 (Sequoia).
Generated from the published advisory. Verify against your own configuration.
