CVE-2026-20628

App sandbox escape via improper permissions

Published Feb 11, 2026 · Updated Feb 11, 2026

Improper access control in Apple Sandbox across affected iOS, iPadOS, macOS, tvOS, visionOS, and watchOS releases allows apps to escape confinement. The Sandbox component applies insufficient permission restrictions, but Apple has not disclosed the defective rule, entitlement, operation, or resource. Exploitation requires a locally executing app and bypasses that app's assigned sandbox boundary; no root access or remote entry is established.
