To based or To be based

[Checkmate]

I searched on Google and there was a result:

Horror Films You Didn't Realize Were Based on True Stories

I would say this is incorrect because "Based" is used as intransitive verb in this sentence. Did this website make a mistake?

Yea, I thought it was an intransitive verb because I couldn't think any object come after 'base'

Does what mean the same thing?

I showed you definition 31, which covers this exact meaning and usage. It is technically intransitive, but the prepositional phrase "on true stories" acts as the object of the verb "based."

[Matthew Wai]

It is technically intransitive

The dictionary below marks it as 'tr.v.', which should stand for 'transitive verb'. Am I wrong?
