ELI5: Why is Adobe Flash so insecure?

It seems like every other day there is an update for Adobe Flash and it’s security related. Why is this?

The "idea" of Adobe Flash was to give websites access to functionality that previously only installed programs had.  This reduced the need to install a bunch of programs and avoided conflicts from having a bunch of programs installed that you weren't using any more.

Alas, this is also exactly what malware wants to do.  The Adobe people can't do the obvious things, like restricting dangerous capabilities, because that undoes the purpose of the program.  That's why many security people say the only safe thing to do with Flash is not use it.
