CNA Information
Analyst Note
Multiple authoritative sources (BleepingComputer) explicitly state CVE-2021-30657 was a zero-day exploited in the wild, fixed by Apple in iOS 15.0.2. Article titles confirm active exploitation preceded or coincided with patch availability (e.g., 'Emergency Apple iOS 15.0.2 update fixes zero-day used in attacks'). The 2021 CVE year aligns with the 2021 patch date, and multiple independent reports confirm exploitation by NSO spyware actors.
