I was surprised to find out that any user can complete or cancel a task regardless of the security privileges set.
I have the activity entity set to read access across the organization, and all other privileges restricted to User.
If user A creates a task and assigns it to User B, I would expect ONLY user B can complete the task, in fact it seems that anyone can complete the task, if they can see it. Am I missing something here?
