Overview
Affected versions of this package are vulnerable to Incorrect Authorization through the normalizeProps() handling in FileActions, PageActions, and UserActions. An authenticated attacker can create or update files, pages, or users with a caller-supplied blueprint payload to override the blueprint used during object creation.
This lets the attacker influence creation-time defaults and options, including bypassing blueprint-defined restrictions such as create: false, and can result in unauthorized content creation or manipulation of the resulting object’s fields and behavior.
