Upload directory has directory listing enabled

Hi,

I hope that you're having a good day

I'm not really sure if this is a permissions error

So I checked-up dfes site and in a result Security tab I got the following

Upload directory has directory listing enabled: https://www.dfes.com/wp-content/uploads/
Includes directory has directory listing enabled: https://www.dfes.com/wp-includes/

Scanned the site already in WP Dashboard and it didn't seem to help, any recommendation?

Thanks
