CVE-2025-31189
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 file quarantine bypass was addressed with additional checks. 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 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 · high confidenceThis is a sandbox escape vulnerability in macOS where a file quarantine bypass allows a malicious application to break out of its sandboxed environment and gain unauthorized access to system resources. The vulnerability involves insufficient validation checks in the file quarantine mechanism that can be exploited to execute code outside the app's sandbox boundaries.

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 go to System Settings > About to view the macOS version numberAffected if The version is earlier than 13.7.5, or falls between 14.0 and 14.7.4, or falls between 15.0 and 15.3 (any version in the range < 13.7.5, >= 14.0 and < 14.7.5, or >= 15.0 and < 15.4)
-
Confirm file quarantine is in useOpen Terminal and run 'xattr -l' on a recently downloaded file from the internet, or check for 'com.apple.quarantine' extended attribute on any downloaded fileAffected if The com.apple.quarantine extended attribute is present on downloaded files (file quarantine is active and the bypass could apply)
-
Identify sandboxed applicationsRun 'ps -ax | grep -i sandboxed' or examine /Applications for apps that commonly use sandboxing (Mail, Safari, third-party App Store apps)Affected if Sandboxed applications are running or installed on the system
A system is affected if it runs any macOS version below 13.7.5, between 14.0-14.7.4, or 15.0-15.3, and has file quarantine active for downloaded content.
