Technical details
The plugin fails to validate authorization and CSRF tokens on its REST endpoint that updates options, and does not restrict the scope of options to those belonging to the plugin itself. This allows unauthenticated attackers to modify arbitrary WordPress options via network requests, leading to privilege escalation and administrative access.
