# Privilege Escalation Through Code Logic

## Overview
Privilege escalation occurs when users can elevate their own access levels through:
- Mass assignment: User profile update endpoint accepts `role` or `isAdmin` fields
- Parameter tampering: Changing `user_id` to another user's ID
- API parameter forgery: Sending `{"role": "admin"}` in user update request

## Remediation
- Explicitly whitelist allowed fields in user update operations
- Never accept role, permission, or admin fields from user-controlled input
- Verify that any elevation action is performed by a sufficiently privileged user
