## Technical details

The plugin's setup handler (admin_setting_setup_data) fails to perform capability checks before processing requests, and the security token it validates is issued to unauthenticated users. An attacker can send a crafted request to overwrite any plugin configuration setting, including those not supplied in the request (causing them to be discarded). The vulnerability is exposed via an HTTP request vector requiring no authentication or user interaction.
