Security readout for executives and security teams
Plain-English summary
A local app on an affected Mac may bypass intended permission restrictions and access sensitive user data. Successful abuse requires user interaction, but the resulting confidentiality impact may be significant. Apple addressed the issue by adding restrictions in specified macOS updates.
Executive priority
Schedule prompt endpoint remediation, accelerating systems containing regulated, confidential, or executive data. The medium score and local interaction requirement reduce urgency relative to remote compromise, but potential disclosure of sensitive data remains material.
Technical view
CVE-2025-43378 is a macOS permissions issue classified as CWE-200. Its CVSS 3.1 score is 5.5: local access, low complexity, no privileges, user interaction, high confidentiality impact, and no identified integrity or availability impact.
Likely exposure
Potential exposure includes Macs running versions earlier than macOS Sequoia 15.7.2 or macOS Tahoe 26.1. The supplied affected-version entries do not provide reliable lower bounds, so exact vulnerable release ranges cannot be determined from this bundle.
Exploitation context
The CVSS vector indicates a malicious local app and user interaction are required. The CVE is not listed as KEV, and the supplied sources do not establish active exploitation, public exploit availability, or remote attackability.
Researcher notes
Public technical detail is limited to a permissions issue addressed through additional restrictions. The exact subsystem, permission boundary, affected lower versions, and exploitation mechanics are not supplied. Testing should focus on version-based exposure and documented Apple behavior without assuming an undocumented attack path.
Mitigation direction
- Update macOS Sequoia systems to 15.7.2 or later.
- Update macOS Tahoe systems to 26.1 or later.
- Prioritize Macs handling sensitive user or business data.
- Consult the linked Apple advisories for deployment guidance and additional restrictions.
Validation and detection
- Inventory macOS editions and versions across managed endpoints.
- Confirm Sequoia endpoints run 15.7.2 or later.
- Confirm Tahoe endpoints run 26.1 or later.
- Verify endpoint management reports successful update installation.
- Investigate unsupported or unclassified macOS versions against current Apple guidance.

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.
