CVE-2026-64710 Overview
CVE-2026-64710 is an information disclosure vulnerability affecting Apple macOS. A local application can leak sensitive user information due to insufficient privacy controls in an affected macOS component. Apple addressed the issue by removing the sensitive data from the exposed interface. The flaw is categorized under [CWE-200] Information Exposure and requires local access with user interaction to exploit.
Critical Impact
A malicious or curious application installed on the system can access sensitive user information without additional privilege, undermining macOS privacy protections.
Affected Products
- Apple macOS Sequoia versions prior to 15.7.8
- Apple macOS Sonoma versions prior to 14.8.8
- Apple macOS Tahoe versions prior to 26.6

Technical Details for CVE-2026-64710
Vulnerability Analysis
CVE-2026-64710 stems from an information exposure weakness in Apple macOS. An installed application can read sensitive user information that should have been restricted by macOS privacy boundaries. Apple's advisory describes the fix as removing the sensitive data from the affected surface, indicating the data was previously reachable without adequate authorization checks.
The issue falls within [CWE-200] Information Exposure. The confidentiality impact is high, while integrity and availability are unaffected. Exploitation does not grant code execution or privilege escalation on its own, but the disclosed data can support secondary attacks such as targeted phishing or credential correlation.
Root Cause
The root cause is a design oversight in which sensitive user data was accessible through an application-reachable interface without appropriate privacy gating. Apple resolved the issue by eliminating that data path in macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, and macOS Tahoe 26.6.
Attack Vector
Exploitation requires local access and user interaction, typically achieved by convincing a user to install or run a malicious application. Once running, the app queries the vulnerable interface and retrieves data outside its normal entitlements. No network access is required, and no elevated privileges are needed prior to exploitation.
No public proof-of-concept code is available for CVE-2026-64710. Refer to the Apple Security Update Advisory for vendor-provided technical context.
Detection Methods for CVE-2026-64710
Indicators of Compromise
- Unsigned or newly installed applications making unexpected calls to system privacy APIs or reading user profile data.
- Applications running outside /Applications that access personal directories such as ~/Library shortly after launch.
- Unusual outbound network traffic from userland processes following access to sensitive local data.
Detection Strategies
- Inventory macOS endpoints and flag hosts running versions earlier than 15.7.8, 14.8.8, or 26.6.
- Monitor process telemetry for non-Apple binaries invoking privacy-sensitive frameworks without a corresponding TCC prompt.
- Correlate application install events with subsequent file access to user data directories.
Monitoring Recommendations
- Enable endpoint telemetry for process execution, file access, and code-signing status on all macOS devices.
- Alert on applications that read sensitive user data but lack a valid developer signature or notarization.
- Review MDM compliance reports weekly to confirm macOS security update deployment.
How to Mitigate CVE-2026-64710
Immediate Actions Required
- Update all macOS endpoints to macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, or macOS Tahoe 26.6.
- Audit installed third-party applications and remove software from untrusted sources.
- Enforce Gatekeeper and notarization requirements through MDM policy.
Patch Information
Apple published fixes in macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, and macOS Tahoe 26.6. Full advisory details are available in the Apple Security Update Advisory 128067, Apple Security Update Advisory 128071, and Apple Security Update Advisory 128072.
Workarounds
- Restrict application installation to signed and notarized software approved by IT.
- Apply least-privilege TCC policies via MDM to limit application access to sensitive user directories.
- Educate users to avoid running untrusted applications until patches are deployed.
# Verify macOS version on endpoints
