EPSS is below 1\u202f%, indicating a low likelihood of exploitation in the wild, and the vulnerability is not listed in the CISA KEV catalog.

Because the flaw only allows read access, an attacker would need a malicious or compromised app installed by the user."}}}}, "created": "2026-03-25T11:36:53.443687+00:00", "title": "macOS Permissions Flaw Allowing Unauthorized Access to Protected User Data", "updated": "2026-03-27T09:20:10.429966+00:00", "vendors": ["apple", "apple$PRODUCT$macos"]}
