Technical details

An input validation vulnerability exists in the way Apple's web components process content, leading to a failure in enforcing Content Security Policy (CSP). By enticing a user to process maliciously crafted web content, a remote attacker can bypass CSP restrictions. This could facilitate cross-site scripting (XSS) or other content-injection attacks that CSP is designed to mitigate. The issue was addressed through improved input validation in Safari 26.5, iOS 18.7.9/26.5, iPadOS 18.7.9/26.5, macOS Tahoe 26.5, tvOS 26.5, visionOS 26.5, and watchOS 26.5.
