Are you talking about search plugins? If you are, that's expected behaviour.
"Note that python plugins/scripts are, by its nature, not considered to be safe. Therefore any use of the unofficial plugins is at your own risk. It is a good practice to audit/take a look at the plugin/script before you install." (From the link)
Have a look at Jackett or Prowlarr (and the rest of the arr suite), it would greatly reduce your attack surface if you are worried about that and they are very easy to set up if you look for the servarr wiki.
