This issue is fixed in macOS Monterey 12.6.8, iOS 15.7.8 and iPadOS 15.7.8, iOS 16.6 and iPadOS 16.6, tvOS 16.6, macOS Big Sur 11.7.9, macOS Ventura 13.5, watchOS 9.6.

An attacker needs only local access with an app that can run on the device, requires no privileges, and needs the user to interact (for example, by opening or running that app).","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-23T07:14:32Z"},"cvss":{"score":5.5,"severity":"MEDIUM","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","provenance":"source","from":"NVD"},"epss":{"score":0.02899,"percentile":0.86944,"date":"2026-10-31","provenance":"source"},"kev":{"dateAdded":"2023-07-26","dueDate":"2023-08-16","ransomware":false,"requiredAction":"Apply
