The flaw stems from missing entitlement checks that were intended to block access to privileged system interfaces. Because those checks are omitted, an application that would normally be denied can be executed with root permissions, allowing an attacker to run arbitrary code on the machine. This weakness is classified as CWE‑280 and represents a privilege‑escalation vulnerability.

macOS installations prior to the patched releases are affected. Specifically, any build of macOS Golden Gate older than version 27, macOS Sequoia older than 15.8, or macOS Tahoe older than 26.7 contains the flaw.

The CVSS score of 7.8 indicates high severity, while the EPSS score of less than 1 % signals a very low likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog, suggesting no known public exploits. Attackers would need to run a specially crafted application that takes advantage of the entitlement bypass; the description explicitly states that an app may gain root privileges. Because root access grants complete system control, the potential impact is severe even though current exploitation indicators remain limited.
