Missing privilege checks in Apple operating systems allow an application to read or write sensitive user data that it should not access. The flaw is a failure to enforce application-level permissions, resulting in a confidential data breach that could expose personal communications, device settings, and other private information. The weakness is characterized as a missing authorization check (CWE‑284).

Vulnerable Apple devices include iOS, iPadOS, macOS, visionOS, and watchOS running versions earlier than iOS 26.7, iPadOS 26.7, macOS Golden Gate 27, Sequoia 15.8, Tahoe 26.7, visionOS 27, and watchOS 27. Any device running a version earlier than these could potentially be compromised by a malicious or overly privileged app.

The CVSS score of 5.5 denotes moderate severity, while the EPSS score of less than 1 % and the absence from CISA’s KEV catalog suggest a low likelihood of real‑world exploitation. The most probable attack vector involves a user installing an app with unverified privileges or an app that falsely requests elevated access. The impact is confidential data loss, but there is little evidence of broader system compromise.
