Does not recognize cforms vulnerablity

I found only this plugin (https://br.www.ads-software.com/plugins/cforms2/) and no other with the name “cforms”. At WP Scan Database there is a report for this plugin (https://wpvulndb.com/search?utf8=%E2%9C%93&text=cforms).

But remembering, this plugin reports information from wpvulndb.com and paid plugins and themes, plugins modified or developed and not published on www.ads-software.com, in most cases do not have their content validated, because their content is not public.
