Unauthorized access via missing capability check

Published Apr 28, 2025 · Updated Apr 28, 2026

Missing authorization in SeventhQueen KLEO before 5.4.4 allows remote attackers to perform an unauthorized action over the network. A theme function omits the capability check that should restrict the action, but published sources do not identify the function or action. No authentication or user interaction is required; the documented consequence is limited to unauthorized access with low confidentiality impact.
