Which of the following CWE vulnerability categories are present in this code? Multiple options may be correct.

  A) CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
  B) CWE-312: Cleartext Storage of Sensitive Information
  C) CWE-1004: Sensitive Cookie Without 'HttpOnly' Flag
  D) CWE-502: Deserialization of Untrusted Data
  E) CWE-377: Insecure Temporary File
  F) CWE-117: Improper Output Neutralization for Logs
Answer: B
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.
