Problem:
How can I prevent that only Post Authors can access the update form?

Solution:
Go to the Toolset → Access Control page and click the Toolset Forms tab and click to expand the "Post Forms Front-end access group" and find your form name and adjust the permissions to "Edit Own" and save the permissions (you should revoke the "Edit Others" permissions).
