Title
Flowintel Organization Administrator Can Reset Full Administrator Password and Escalate Privileges
Summary
Affected versions of Flowintel contain an authorization flaw in the administrative user-edit API.
The existing authorization check correctly prevented an organization administrator from editing users in another organization, but it did not prevent them from editing a full administrator within their own organization. As a result, an org admin could modify that full administrator account, including changing its password. The upstream commit explicitly describes the issue as:
“Org admin can change the password of a full admin in the same organization.”
The fix adds a higher-privilege boundary check:
if user_to_edit.is_admin(): return ... 403
so organization administrators can no longer modify full administrator accounts.
Version impacted >=3.3.0
