Summary
The BE REST Endpoints WordPress plugin through 1.0.0 does not perform any authorization check before allowing widgets to be read, created, updated and deleted, and does not sanitize the values it stores in them, allowing unauthenticated users to inject arbitrary web scripts which will execute in the browser of any user visiting the site.
