RISK

Why user_permissions_create is rated Medium

This tool creates new user permissions in Google Tag Manager, which is a reversible modification of system state (access can be revoked). The high severity reflects that granting inappropriate access to GTM accounts could expose sensitive tracking infrastructure, data collection rules, and potentially lead to unauthorized modifications of analytics configurations.

From the tool's definition Tool name contains 'create' and description explicitly states '[WRITE] Grant a user access to a GTM account'. The description indicates this tool creates new permission grants, modifying access control state.
