A logic issue was addressed with improved validation. This issue is fixed in macOS Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26. A malicious app may be able to access sensitive user data.
AnalysisAI
Improper authorization in Apple macOS allows a locally-installed malicious application to access sensitive user data without proper entitlement checks. Affected releases span three macOS generations: Sequoia (prior to 15.7), Sonoma (prior to 14.8), and the forthcoming Tahoe (prior to 26). The flaw stems from a logic issue in access validation, meaning apps lacking legitimate permissions can bypass gating controls to read protected data. No public exploit code or CISA KEV listing has been identified at time of analysis.
Technical ContextAI
The vulnerability is rooted in CWE-285 (Improper Authorization), specifically a logic flaw in macOS's access validation layer that fails to correctly enforce data access permissions for third-party applications. CPE data (cpe:2.3:a:apple:macos:*:*:*:*:*:*:*:*) confirms the affected surface is the macOS platform broadly rather than a single subsystem. Apple's sandboxing and TCC (Transparency, Consent, and Control) framework is the expected enforcement boundary for sensitive user data access; a logic error here would allow an app to read protected categories - such as contacts, photos, location, or health data - without having been granted the corresponding entitlement or user consent. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms exploitation requires local execution context with low-privilege user access, consistent with a sandboxed app scenario.
RemediationAI
The primary fix is to upgrade to a patched macOS release: macOS Sonoma 14.8, macOS Sequoia 15.7, or macOS Tahoe 26, all of which include Apple's corrected validation logic. Patch details are available through Apple's security advisories at https://support.apple.com/en-us/125110 (Sonoma), https://support.apple.com/en-us/125111 (Sequoia), and https://support.apple.com/en-us/125112 (Tahoe). As a compensating control prior to patching, administrators and users should audit installed third-party applications and revoke unnecessary TCC permissions via System Settings > Privacy & Security, limiting app access to sensitive data categories (Contacts, Photos, Calendar, etc.) only where strictly required. This reduces the data surface accessible to a potentially malicious app but does not eliminate the underlying logic flaw. Organizations managing fleets should prioritize deployment of the patches via MDM solutions given the zero-interaction exploitation path once an app is installed.
