Security readout for executives and security teams
Plain-English summary
A macOS app may bypass intended permission boundaries and read sensitive user data after a user interacts with it. Apple corrected the permissions issue in specified macOS updates. The principal business risk is confidentiality loss on unpatched Macs; the supplied evidence does not indicate data modification, service disruption, or active exploitation.
Executive priority
Prioritize deployment through normal security-update processes, accelerating systems handling regulated, confidential, or executive data. Emergency response is not supported by the supplied evidence, but delayed patching leaves a plausible path for malicious applications to expose sensitive information.
Technical view
CVE-2025-43479 is a local information-disclosure issue categorized as CWE-200. Its CVSS 3.1 score is 5.5: exploitation requires local execution and user interaction, needs no privileges, has low complexity, and may cause high confidentiality impact without integrity or availability impact.
Likely exposure
Macs running releases older than macOS Sequoia 15.7.2, Sonoma 14.8.2, or Tahoe 26.1 may be exposed. The supplied affected-version data is incomplete, so exact vulnerable version ranges and the specific permission boundary cannot be confirmed.
Exploitation context
The supplied record does not identify CVE-2025-43479 as a CISA KEV vulnerability and provides no evidence of active exploitation or public exploit availability. Exploitation requires a user to interact with a locally running app, limiting remote reach but preserving meaningful phishing or malicious-app risk.
Researcher notes
Public details are sparse: Apple describes additional permission restrictions but does not identify the affected component, data class, root cause, or precise vulnerable ranges in the supplied bundle. CVSS indicates local, low-complexity access with user interaction and no required privileges. Treat deeper exploitability conclusions as unverified.
Mitigation direction
- Update Sequoia systems to macOS 15.7.2 or later.
- Update Sonoma systems to macOS 14.8.2 or later.
- Update Tahoe systems to macOS 26.1 or later.
- Review Apple guidance before handling macOS branches not identified in the supplied sources.
Validation and detection
- Inventory macOS versions across managed and unmanaged endpoints.
- Confirm each device meets its applicable fixed release or a later version.
- Verify update compliance through endpoint-management reporting.
- Investigate sensitive-data access alerts involving locally executed, user-opened applications.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
