Isn't there a risk, that someone can (accidentally or not) enter hash-code of someone else's "closure"?

[mdakin → malkia]

One could avoid that problem by keeping track of the owner of each closure and ensuring the user is properly authenticated before calling the closure.

[pg → malkia]

The code explicitly protects against that.

If access to the closures are session-specific, you'll have to hijack the session to do that.
