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 CWE vulnerability categories are present in this code? Multiple options may be correct.

  A) CWE-312: Cleartext Storage of Sensitive Information
  B) CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
  C) CWE-918: Server-Side Request Forgery (SSRF)
  D) CWE-20: Improper Input Validation
  E) CWE-643: Improper Neutralization of Data within XPath Expressions ('XPath Injection')
  F) CWE-732: Incorrect Permission Assignment for Critical Resource
Answer: D
system: You are an expert security code reviewer. You will be shown a source code file along with a multiple-choice question listing several function or class names from that file. Your task is to identify which one contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the single letter of the correct option, wrapped in \boxed{...}. Example: `\boxed{B}`. Output the boxed letter ONLY -- no explanation, no other text.

user: ```python
import re
from .mappings import lat2cir, bi2mono

def clean(text):
    """ Clean text and convert everything to uppercase. """
    text = text.upper()
    return re.sub(r'[~`!@#$%^&*()-=_+\{\}\[\]\\:\;\"\'\|\?\>\<\,\.\/QWXY]+', " ", text)

def convert2cir(text):
    """ Convert Latin script to Cyrilic."""
    for i, j in lat2cir.iteritems():
        text = text.replace(i, j)
    return text

def convert_to_monographeme(text):
    """ Convert bigraphemes to single Cyrilic."""
    for i, j in bi2mono.iteritems():
        text = text.replace(i, j)
    return text

    """ Call all helper functions to convert Latin to Cyrilic uppercase and return list of strings. """
    return [x for x in convert_to_monographeme(convert2cir(clean(text))).split(' ') if x]

```

Which of the following functions or classes contains a `CWE-20: Improper Input Validation` vulnerability?

  A) clean
  B) convert_all
  C) convert_to_monographeme
  D) convert2cir
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
import re
from .mappings import lat2cir, bi2mono

    """ Clean text and convert everything to uppercase. """
    text = text.upper()
    return re.sub(r'[~`!@#$%^&*()-=_+\{\}\[\]\\:\;\"\'\|\?\>\<\,\.\/QWXY]+', " ", text)

def convert2cir(text):
    """ Convert Latin script to Cyrilic."""
    for i, j in lat2cir.iteritems():
        text = text.replace(i, j)
    return text

def convert_to_monographeme(text):
    """ Convert bigraphemes to single Cyrilic."""
    for i, j in bi2mono.iteritems():
