CVE-2025-22484Network attack vector

Authenticated resource-access interruption via unbounded allocation

Published Jun 6, 2025 · Updated Jun 6, 2025

Resource exhaustion in QNAP File Station 5 5.5.x before 5.5.6.4847 allows remote authenticated users to interrupt resource access. The vendor says the application allocates a resource without limits or throttling but has not disclosed the affected request, resource type, or code locus. A valid user account is required; exploitation prevents other systems, applications, or processes from accessing the same resource type.
