Authenticated service interruption via unbounded resource allocation
Published Aug 29, 2025 · Updated Aug 29, 2025
Resource exhaustion in QNAP File Station 5 5.5.x before 5.5.6.4907 allows remote authenticated users to interrupt file services. QNAP has not disclosed the affected request, function, or resource whose allocation lacks an enforced limit or throttle. A valid user account is required, and successful exploitation exhausts a shared resource so other systems, applications, or processes cannot access it.
