// React component with intentional vulnerabilities and issues
import React, { useState, useEffect } from 'react';
import axios from 'axios';

// ISSUE: Hardcoded API endpoint
const API_BASE_URL = 'https://api.example.com';

// ISSUE: No error handling, missing keys, performance issues
function UserList({ userId }) {
  const [users, setUsers] = useState([]);
  const [loading, setLoading] = useState(false);
  const [searchTerm, setSearchTerm] = useState('');

  // ISSUE: Missing dependency array, potential memory leak
  useEffect(() => {
    fetchUsers();
  });

  // ISSUE: SQL injection vulnerability, no input validation
  const fetchUsers = async () => {
    setLoading(true);
    try {
      // ISSUE: Direct string concatenation with user input
      const response = await axios.get(`${API_BASE_URL}/users?search=${searchTerm}`);
      setUsers(response.data);
    } catch (error) {
      // ISSUE: Logging sensitive information
      console.log('Error fetching users:', error.response.data);
    } finally {
      setLoading(false);
    }
  };

  // ISSUE: Inefficient filtering, no memoization
  const filteredUsers = users.filter(user => 
    user.name.toLowerCase().includes(searchTerm.toLowerCase())
  );

  // ISSUE: Missing key prop, potential XSS vulnerability
  const renderUsers = () => {
    return filteredUsers.map(user => (
      <div className="user-card">
        <h3>{user.name}</h3>

        <button onClick={() => deleteUser(user.id)}>
          Delete User
        </button>
      </div>
    ));

  // ISSUE: No authentication check, direct API call
  const deleteUser = async (id) => {
    try {
      await axios.delete(`${API_BASE_URL}/users/${id}`);
      setUsers(users.filter(user => user.id !== id));
    } catch (error) {
      // ISSUE: Exposing internal error details
      alert(`Error: ${error.response.data.message}`);
    }

  // ISSUE: Inline styles, no CSS optimization
