CVE-2025-24208Network attack vector

Cross-site scripting via insufficient iframe permissions

Published Mar 31, 2025 · Updated Apr 2, 2026

Cross-site scripting in WebKit in Apple Safari, iOS, and iPadOS before 18.4 allows remote attackers to execute script via a malicious iframe. WebKit applies insufficient permission restrictions while loading the crafted iframe, but Apple has not identified the affected code path or permission decision. Exploitation requires a user to load attacker-controlled web content and permits script execution across an origin boundary, enabling access to or modification of data available to the impersonated origin.
