CVE-2025-43411

Vulnerability

Overview CVE-2025-43411 is a logic issue in macOS entitlement checks that could allow an application to access user-sensitive data without proper authorization. The root cause is insufficient validation of entitlements, which are permissions granted to apps for accessing protected resources.

Exploitation

An attacker would need to have an app installed on the target system; no special privileges are required beyond that. The app could craft requests or operations that bypass the entitlement verification, enabling unauthorized access to sensitive data. The vulnerability is local in scope and does not require network access.

Impact

Successful exploitation allows an app to read user-sensitive data, such as documents, contacts, or other information protected by macOS privacy controls. The exact scope of accessible data is not detailed, but it could include personal files or system-level information.

Mitigation

Apple addressed this issue with improved entitlement checks in macOS Tahoe 26.1, macOS Sequoia 15.7.2, and macOS Sonoma 14.8.2, all released on November 3, 2025 [1][2][3]. Users should update their systems to these versions to mitigate the risk.
