Authenticated unauthorized resource access
Published Aug 6, 2025 · Updated Aug 6, 2025
Authorization bypass in Emby Server 4.9.0.35 allows remote authenticated users to gain unauthorized access via user-controlled keys. The CNA-linked disclosure does not identify the affected endpoint, key, protected object, or failed authorization operation, and Emby disputes that the record describes a valid flaw. Low-privileged network access is the published gate, but the specific data or functions exposed and the operational consequences remain undisclosed.
