Overview

Affected versions of this package are vulnerable to Incorrect Authorization through the bulk-access process. An attacker can gain unauthorized access to confidential information, modify permission settings, and remove legitimate users' access by directly invoking the API with manipulated collectionIds and user assignments. This is only exploitable if the attacker holds a Manager role within the target organization and targets collections not originally assigned to them.
