CVE-2026-43713 is a WebKit vulnerability affecting Safari, iOS, iPadOS, macOS Tahoe, tvOS, visionOS, and watchOS. The issue is described as a permissions flaw that was addressed by adding additional restrictions. A user visiting a malicious website may trigger unintended access to protected data, resulting in leakage of sensitive information. The available information indicates the bug resides in WebKit permission enforcement rather than memory safety, but no vulnerable function or lower-level root cause details are currently available.
