Technical details
The GET /layout/status/{id} endpoint lacked access control checks prior to version 4.4.3, allowing any authenticated user to retrieve layout status and metadata without verifying view permissions. The fix adds a checkViewable() permission check before processing the request. An authenticated attacker with any privilege level can exploit this with a network request to enumerate and view restricted layouts.
