Authenticated service interruption via unrestricted resource allocation
Published Jan 2, 2026 · Updated Jan 2, 2026
Resource exhaustion in QNAP QTS and QuTS hero allows remote authenticated users to interrupt access to a shared resource. The vendor identifies unrestricted allocation of an unspecified resource but does not disclose the affected component, request, or allocation operation. A valid user account is required, and exhaustion denies the same resource type to other systems, applications, or processes without reported confidentiality or integrity impact.
