CVE-2022-26694
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 with improved checks. This issue is fixed in macOS Monterey 12.4. A plug-in may be able to inherit the application's permissions and access user data.
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 allows plug-ins to improperly inherit the host application's permissions, potentially enabling unauthorized access to user data. The fix in macOS Monterey 12.4 added improved permission checks to prevent this privilege escalation via plug-ins.

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.
-
Determine macOS versionRun 'sw_vers -productVersion' in Terminal or check System Settings > AboutAffected if Version is 12.0.0, 12.1.x, 12.2.x, or 12.3.x (falls within >= 12.0.0 and < 12.4)
-
Identify installed plug-insReview applications that use plug-in architectures (common locations: ~/Library/Application Support/, /Library/Application Support/, or within app bundles in /Applications/)Affected if Any third-party applications with plug-in extensions are installed
System is affected if running macOS Monterey versions 12.0.0 through 12.3.x and any applications with plug-in functionality are in use, as the vulnerability allows those plug-ins to improperly inherit host application permissions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped12.4
Apply macOS Monterey 12.4 or later. For developers, audit plug-in architectures to ensure proper permission isolation and avoid inheriting parent application privileges.
macOS Monterey 12.4
