Sensitive user data disclosure via insufficient permission checks

Published Dec 17, 2025 · Updated Dec 17, 2025

Improper access control in WebKit in Apple macOS and Safari before 26.2 allows local users to read sensitive user data through an app. The WebKit component performs insufficient permission checks when an app requests protected data, but Apple has not disclosed the affected API or data class. Execution of an app on macOS is required; the disclosed consequence is read-only access to unspecified sensitive user data.
