Administrator-triggered resource exhaustion via unbounded allocation
Published Feb 11, 2026 · Updated Feb 11, 2026
Resource exhaustion in QNAP Qsync Central 5.0.x allows remote authenticated users with administrator access to interrupt services. QNAP has not disclosed the affected request handler, resource type, or operation that allocates resources without a limit or throttle. Administrator-level credentials and unspecified attack conditions are required, and exploitation denies the same resource to other systems, applications, or processes.
