A logic issue was addressed with improved state management. This issue is fixed in macOS Monterey 12.3, Safari 15.4, watchOS 8.5, iOS 15.4 and iPadOS 15.4, tvOS 15.4. A malicious website may cause unexpected cross-origin behavior.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A logic error in Safari and Apple operating systems allowed a malicious website to perform unexpected cross-origin actions, potentially bypassing Same-Origin Policy protections. This state management flaw could enable unauthorized communication or data access between different origins.

MitigationUpdate affected devices to Safari 15.4, macOS Monterey 12.3, iOS/iPadOS 15.4, watchOS 8.5, or tvOS 15.4 and later to obtain the patched version with improved state management for cross-origin restrictions.
