The vulnerability does not enable arbitrary code execution or privilege escalation but exposes a unique device identifier that could be used for tracking, profiling, or linking user activity across services.

The EPSS score of less than 1% suggests that real\u2011world exploitation is unlikely at present. The vulnerability is not listed in CISA\u2019s KEV catalog. It can be exploited by any application on the device that gains authorization to read device identifiers, meaning the threat vector is local, arising from any installed app. Because the flaw does not require additional conditions such as network access or user interaction beyond normal permission usage, it is relatively easy for an attacker who controls an app to read the identifier.\n"}}}}, "created": "2026-04-28T11:30:29.837157+00:00", "title": "Permissions Flaw Exposes Persistent Device Identifier in iOS and iPadOS", "updated": "2026-04-28T11:30:29.837166+00:00", "vendors": []}
