This privacy breach can expose sensitive personal information and browsing habits. The weakness is a classic example of an authentication bypass, classified as CWE-285.

The EPSS score of less than 1% suggests that exploitation is unlikely at present, and the vulnerability is not listed in CISA's KEV catalog. The most probable attack vector is local, where a user installs or uses an app that can read Safari history after the logic error is triggered. No additional conditions are required beyond the presence of an affected app.\n"}}}}, "created": "2026-02-12T09:02:47.904285+00:00", "updated": "2026-04-15T21:15:13.571762+00:00", "vendors": ["apple", "apple$PRODUCT$ios_and_ipados", "apple$PRODUCT$macos", "apple$PRODUCT$safari"]}
