Lifecycle Timeline
2DescriptionCVE.org
This issue was addressed with improved data protection. This issue is fixed in macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2. An app may be able to access sensitive user data.
AnalysisAI
Improper data access control in macOS allows local applications to read sensitive user data without explicit user consent, exploitable through user interaction. The vulnerability affects macOS Sequoia (before 15.7.3), macOS Sonoma (before 14.8.3), and macOS Tahoe (before 26.2). No public exploit code or active exploitation has been identified; EPSS probability is extremely low at 0.01%, indicating minimal real-world attack likelihood despite the moderate CVSS score.
Technical ContextAI
This vulnerability is rooted in CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), reflecting a data protection failure at the operating system level. The underlying issue stems from inadequate access controls or sandbox restrictions that govern inter-process communication and file system permissions on macOS. The affected systems span multiple major macOS versions (Sequoia, Sonoma, and Tahoe), indicating a systemic flaw in how the OS enforces confidentiality boundaries between applications and sensitive user data stores. The fix is categorized as 'improved data protection,' suggesting Apple strengthened either the visibility rules for sensitive data, refined privilege escalation checks, or hardened the app sandbox enforcement mechanisms.
RemediationAI
Vendor-released patches are available: macOS Sequoia users should update to version 15.7.3 or later, macOS Sonoma users should update to version 14.8.3 or later, and macOS Tahoe users should update to version 26.2 or later. Updates can be obtained through System Settings > General > Software Update on affected systems. No workarounds are documented for systems unable to immediately patch; users should restrict local access to their systems and avoid granting elevated privileges to untrusted applications.
