Summary

APITable through 1.13.0-beta.1 contains an incorrect authorization vulnerability in NodePermissionGuard that fails to enforce node-level access control when permission lookups throw exceptions. Attackers with valid Fusion API tokens can write attachments to private datasheets they have been explicitly denied access to by exploiting the unhandled exception in the permission guard.
