Name the function or class in this code that contains a `CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')` vulnerability.
Answer: post
system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

OUTPUT FORMAT: Respond with the letter(s) of all correct options, sorted alphabetically and comma-separated, wrapped in a single \boxed{...}. Examples: `\boxed{A}` for one correct, `\boxed{A,C}` for two, `\boxed{A,C,E}` for three. Output the boxed answer ONLY -- no explanation, no other text.

Which of the following functions or classes contains a `CWE-209: Generation of Error Message Containing Sensitive Information` vulnerability?

  A) predict
  B) result
  C) index
Answer: A
system: You are an expert security code reviewer. You will be shown a source code file. Your task is to name the single function or class that contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the exact function or class name (no parentheses, no qualifiers, no module prefixes), wrapped in \boxed{...}. Example: `\boxed{salted_hmac}`. Output the boxed name ONLY -- no explanation, no other text.

user: ```python
from flask import Flask, render_template, request, abort
from utils.downloader import download_img,download_thumbnail
import sys
from evaluate import evaluate, mobilenet, nasnet
import os
import json

app = Flask(__name__)
fn = "temp/flask_test.jpg"
model = mobilenet()
model._make_predict_function()
#model2 = nasnet()
#model2._make_predict_function()
test = "teeest"

@app.route('/',methods=['GET'])
def index():
    test = "teeest"
    return render_template('index.html')

@app.route('/', methods=['POST'])
