Information Exposure

Affected versions of this package are vulnerable to Information Exposure. When the format functionality of Python is utilized, an individual controlling the format string can access objects via attribute access and subscription from accessible objects. This access uses Python's getattr and getitem, not the policy restricted AccessControl variants _getattr_ and _getitem_. This could potentially lead to critical information disclosure.

How to fix Information Exposure?

Upgrade AccessControl to version 4.4, 6.2 or higher.
