DescriptionCVE.org

The issue was addressed with improved checks. This issue is fixed in Safari 26.5.2, iOS 26.5.2 and iPadOS 26.5.2, macOS Tahoe 26.5.2. A malicious website may be able to process restricted web content outside the sandbox.

AnalysisAI

Sandbox escape in Apple's WebKit/Safari web content engine allows a malicious website to process restricted web content outside the sandbox on Safari, iOS/iPadOS, and macOS prior to 26.5.2. Reported by Apple and classed as an improper access-control flaw (CWE-284), it requires a victim to load attacker-controlled content (UI:R) and carries CVSS 7.1 with a scope change, reflecting that breaking out of the sandbox crosses a security boundary. There is no public exploit identified at time of analysis and EPSS is low (0.16%), though CISA's SSVC framework rates the technique as automatable with partial technical impact.
