Authenticated service interruption
Published Feb 11, 2026 · Updated Feb 11, 2026
Allocation without limits in QNAP Qsync Central 5.0.x before 5.0.0.4 allows remote authenticated users to interrupt resource access. QNAP has not disclosed the affected component, resource type, request, or operation that permits unbounded allocation, so the concrete trigger is not public. A valid user account is required; exploitation denies other systems, applications, or processes access to the exhausted resource, without reported data disclosure or modification.
