Lifecycle Timeline
2DescriptionCVE.org
A permissions issue was addressed with additional restrictions. 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
Local privilege escalation in macOS allows authenticated applications to access sensitive user data through insufficient permission restrictions on Sequoia, Sonoma, and Tahoe versions. The vulnerability requires local access and low-privilege user context but enables high-impact confidentiality compromise without requiring user interaction or elevated privileges to trigger. A vendor-released patch is available across all affected macOS versions.
Technical ContextAI
This vulnerability exploits improper permission controls in macOS's access control framework, classified under CWE-276 (Incorrect Default Permissions). The underlying issue involves insufficient restriction on inter-process communication or file system access permissions that allow unprivileged application processes to read sensitive user data normally protected by macOS's sandbox and permission model. The affected CPE entries indicate the vulnerability spans multiple macOS major versions (Sequoia 15.x, Sonoma 14.x, and Tahoe 26.x), suggesting a systemic permissions configuration issue rather than a single component flaw.
RemediationAI
Vendor-released patches are available for all affected macOS versions: upgrade to macOS Sequoia 15.7.3 or later, macOS Sonoma 14.8.3 or later, or macOS Tahoe 26.2 or later. Users should apply these security updates immediately via System Settings > General > Software Update. No workarounds are documented for this permission-based issue prior to patching. Refer to Apple Security Advisory HT125886 for Sequoia, HT125887 for Sonoma, and HT125888 for Tahoe for detailed remediation guidance and build verification.
