CVE-2026-7402Network attack vector

Authenticated service disruption via request flooding

Published Apr 30, 2026 · Updated Apr 30, 2026

Improper interaction-frequency control in MeWare PDKS before VMYR_3.5.2025117 allows remote authenticated users to flood the service. The public CNA record identifies flooding but does not disclose the affected component, request type, or operation that fails to limit repeated interactions. Low-privileged network access is required; successful flooding can alter service state and interrupt availability, while no confidentiality impact is reported.
