An application can hijack entitlements that are normally reserved for other privileged applications, allowing it to gain elevated privileges without proper authorization. This weakness is rooted in inadequate data protection, which permits the malicious app to intercept and misuse entitlement information. The resulting compromise can lead to unauthorized access to system resources, potential data exposure, and intervention in core system services. The identified weakness corresponds to CWE‑266, Designating the failure as incorrect privilege management.

Apple macOS versions prior to macOS Sequoia 15.6 and macOS Sonoma 14.7.7 are affected. Systems running earlier releases are vulnerable to entitlement hijacking until they receive the mentioned updates.

The vulnerability carries a CVSS score of 5.1 and an EPSS of less than 1 %, indicating low but non‑zero exploitation probability. It is not listed in the CISA KEV catalog. The most likely attack vector is local execution: a malicious application installed or run on the machine can exploit the flaw. No evidence suggests remote exploitation, but the presence of elevated privileges offers significant risk if a local attacker succeeds.
