AnalysisAIv1 – Sep 15, 2026

Processing maliciously crafted web content in Apple's WebKit-based browser stack can disclose sensitive user information across Safari 27, iOS/iPadOS 27, macOS Golden Gate 27, tvOS 27, visionOS 27, and watchOS 27 and earlier. Apple classifies the root cause as an improper privilege management (permissions) issue and fixed it by removing the vulnerable code rather than adding a check, per the vendor advisories referenced for CVE-2026-64753. Real-world urgency is currently low: EPSS is 0.14% (4th percentile), there is no CISA KEV listing or public exploit identified at time of analysis, and CISA's SSVC assessment is exploitation:none / automatable:no / technical impact:partial, while a vendor patch is already available.
