Arbitrary file upload in YZNCMS 2.0.1 allows attackers to execute server-side code by installing a crafted ZIP plugin. The plugin installation path processes the crafted archive without blocking an uploaded payload from becoming executable server-side code. Exploitation requires access to plugin installation; published material does not identify the exact required role or whether debug mode must be enabled.
