CWE	CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes
OWASP	A08:2021 - Software and Data Integrity Failures
Confidence Level	Low
Impact Level	Medium
Likelihood Level	Low

Description

Allowing sensitive attributes like :admin, :role, :banned, or :account_id to be mass assigned via permit or attr_accessible exposes your app to attackers who can modify these fields through crafted requests. Using params.permit! is especially risky as it permits all input fields without restriction.

Impact

If exploited, attackers could escalate their privileges, ban users, or hijack other accounts by manipulating these critical attributes. This could lead to unauthorized access, data breaches, or loss of control over user roles and permissions within the application.
